Description
Technical field
The present invention relates to a kind of washing composition, be specifically related to a kind of mercury pollution waste material of buildings washing composition.
Background technology
Mercury pollution, mercury is one of heavy metal element that environment toxic is the strongest, and it has persistence, long-distance migration and bioconcentration, can change into the methyl mercury of severe toxicity at occurring in nature, and the highly enriched and amplification by food chain.As maximum mercury production in the world, use and discharge state, mercury thermometer is used in a large number by China, and China has become the most serious area of global mercury pollution.
The discharge of mercury comes from natural source and artificial source two parts, natural source comprises: volcanicity, weathering, soil discharge and vegetation release etc., the mercury emissions referred to because mankind's activity causes is discharged in artificial source, comprises in the middle of the use of mercury, material containing the mercury emissions three major types that mercury impurities and refuse process cause.
There is more conforming understanding to the source of pollution formation of mercury emissions and the relative importance of each source of pollution, mainly come from combustion of fossil fuel to the mercury emissions in air, especially the burning of coal, and coal-burning power plant is the maximum source of global mercury emissions in air.The total mercury of the artificial emission source discharge in nineteen ninety-five Europe is 341.8 tons, and the mercury of wherein coal-burning power plant's discharge accounts for 26%, occupies the first place of known source of pollution.Other source of pollution also comprise various coal-burned industrial boilers, trash burning, mercury process chlor-alkali production, manufacture of cement, nonferrous production, Iron and Steel Production etc. beyond power plant.
The burning of coal and oil, the smelting of mercurous metalliferous mineral and be the waste gas that the industrial production of raw material is discharged with mercury are the main sources of mercury in air; Using mercurous agricultural chemicals and mercury-containing sludge fertilizer, is the main source of mercury in soils; The waste water of the discharge such as chlorine industry, plastics industry, battery industry and electronic industry is the main source of Mercury in Water Body.
China is that mercury is produced and uses big country, data presentation 2005,2006, and mercury in China output accounts for about 60% of global total mercury output, and mercury demand accounts for 30% ~ 40%, all occupies first place, the whole world.Meanwhile, China is also global mercury emissions big country.End 2010, the annual human activity in the whole world has 2000 tons to the mercury emission of air, and wherein China's annual discharge mercury is about 500-600 ton, account for global mercury emissions total amount 1/4 more than.
To the process of mercury pollution, focus mostly at soil and water source, and the domestic and international improvement to mercury contaminated soil is for some time, and existing many sections of public technology bibliographical informations.Conventional clean-out system comprises water, acid, salts solution, sequestrant, tensio-active agent etc.But the disposal applications at present for mercury pollution waste material of buildings rarely has report; and when existing heavy-metal contaminated soil clean-out system is applied to waste material of buildings; cleaning performance is not good; there is the residual of mercury element more; for the protection to environment, be necessary to study the good washing composition of a kind of cleaning performance for mercury pollution waste material of buildings.
Summary of the invention
The object of the invention is to solve that above-mentioned prior art exists without mercury pollution waste material of buildings special purpose detergent, the deficiency that heavy-metal contaminated soil clean-out system is not good to waste material of buildings cleaning performance, provides a kind of, mercury pollution waste material of buildings washing composition that cleaning performance good high to mercury cleaning efficiency.
A kind of mercury pollution waste material of buildings washing composition, special character is to be prepared from by the raw material of following weight: (R)-N-tertbutyloxycarbonyl-2-benzene glycinol 40-45 part, 3-ethoxy ethyl acrylate 28-35 part, 3, 7-dimethyl-6-octene-3-alcohol 15-18 part, 4-acetamido-2-ethoxy-benzoic acid methyl ester 30-35 part, 1-benzyl ring pentane-1-carboxylic acid 2-(2-diethylin oxyethyl group) ethyl ester 28-32 part, N-[4-[(2-amino-5-formyl radical-4-oxo-1, 6, 7, 8-tetrahydrochysene-6-pteridyl) methyl] amino] benzoyl-Pidolidone calcium salt 20-23 part, acexamic acid 18-24 part, (2S)-2-[[(4S)-4-amino-5-hydroxyl-5-oxo valeryl] is amino]-4-methylvaleric acid 12-15 part.
Preferably, the mercury pollution waste material of buildings washing composition adopting the raw material of following weight to prepare has better washing effect, (R)-N-tertbutyloxycarbonyl-2-benzene glycinol 42 parts, 3-ethoxy ethyl acrylate 28 parts, 3, 7-dimethyl-6-octene-3-alcohol 18 parts, 4-acetamido-2-ethoxy-benzoic acid methyl ester 35 parts, 1-benzyl ring pentane-1-carboxylic acid 2-(2-diethylin oxyethyl group) ethyl ester 32 parts, N-[4-[(2-amino-5-formyl radical-4-oxo-1, 6, 7, 8-tetrahydrochysene-6-pteridyl) methyl] amino] benzoyl-Pidolidone calcium salt 20 parts, acexamic acid 22 parts, (2S)-2-[[(4S)-4-amino-5-hydroxyl-5-oxo valeryl] is amino]-4-methylvaleric acid 12 parts.
Further, in order to obtain the higher mercury pollution waste material of buildings washing composition of cleaning efficiency, described mercury pollution waste material of buildings washing composition also comprises the raw material of following weight: 5-[(3-carboxyl-4-hydroxy phenyl) (3-carboxyl-4-oxo-2,5-cyclohexadiene-1-subunit) methyl]-2 hydroxybenzoic acid three ammonium 13-17 part, Tri(Hydroxymethyl) Amino Methane Hydrochloride 6-10 part, 3-methyl-2-amyl group-2-cyclopentene-1-one 8-12 part.
Preferably, mercury pollution waste material of buildings washing composition, its parts by weight of raw materials proportioning is: 5-[(3-carboxyl-4-hydroxy phenyl) (3-carboxyl-4-oxo-2,5-cyclohexadiene-1-subunit) methyl]-2 hydroxybenzoic acid three ammonium 15 parts, Tri(Hydroxymethyl) Amino Methane Hydrochloride 6 parts, 3-methyl-2-amyl group-2-cyclopentene-1-one 8 parts.
In addition, washing composition of the present invention preferably containing tensio-active agent and/or sequestrant, improves washing effect thus.
Again preferably, described tensio-active agent and/or sequestrant weight are 2-6 part.Its content very easily bubbles time many, and time few, washing effect reduces.
Preparation method of the present invention: add pure water, add (R)-N-tertbutyloxycarbonyl-2-benzene glycinol, 3-ethoxy ethyl acrylate, 3 while stirring, 7-dimethyl-6-octene-3-alcohol, continues to be stirred to and is uniformly dispersed, and is then heated to 60-70 DEG C; Slowly add 4-acetamido-2-ethoxy-benzoic acid methyl ester, 1-benzyl ring pentane-1-carboxylic acid 2-(2-diethylin oxyethyl group) ethyl ester, stir and make it to dissolve; After add N-[4-[(2-amino-5-formyl radical-4-oxo-1 successively, 6,7,8-tetrahydrochysene-6-pteridyl) methyl] amino] benzoyl-Pidolidone calcium salt, acexamic acid, (2S)-2-[[(4S)-4-amino-5-hydroxyl-5-oxo valeryl] is amino]-4-methylvaleric acid, stir; Be cooled to 25-30 DEG C, stir and leave standstill 45-60 minute, namely obtain required mercury pollution waste material of buildings washing composition.
This mercury pollution waste material of buildings washing composition, directly can clean use to waste material of buildings, and operation sequence is simple, to buildings without any corrosive effect.And this washing composition has the removal effect of more than 95% for the mercury element in mercury pollution waste material of buildings, cleaning efficiency is high, and removal effect is good, is suitable for wide popularization and application in mercury pollution waste material of buildings field of Environment Protection.
