Three, above-mentioned borosilicate glass bottle is placed in oscillator, revolving speed 150rpm, temperature is 25 DEG C, reaction time 240min.
3 data of table are obtained through detection.
Removal rate of the different permonosulphuric acid potassium dosages of table 3 to 1,4-D
Table 3 the result shows that, under conditions of activator dosage of the invention is fixed as 1.0g/L, increase permonosulphuric acid
The removal rate of 1,4-D can be improved in the concentration of potassium.Wherein, when permonosulphuric acid potassium concn is 16.0mmol/L, P700/ permonosulphuric acid potassium
The removal rate of system and E700/ permonosulphuric acid potassium system para-dioxane is respectively up to 88.8% and 51.1%.
Embodiment 4
The present embodiment utilizes the step in a kind of charcoal/permonosulphuric acid potassium system efficient degradation water in the method for Isosorbide-5-Nitrae-D,
Compare different preparation temperature charcoals, to the removal rate of Isosorbide-5-Nitrae-D when being added permonosulphuric acid potassium:
Step 1: weighing pine needle charcoal and the phoenix that 20.0mg preparation temperature is 300,400,500,600,700,800 DEG C
Eye lotus charcoal is respectively placed in borosilicate glass bottle of the 22.0mL with screw lid；Step 2, in above-mentioned 22.0mL borosilicic acid
The water of-the D of Isosorbide-5-Nitrae containing 1.76mg/L and the permonosulphuric acid potassium of 8.0mmol/L, pH 6.5 are added in salt vial；Step 3, directly
Borosilicate glass bottle is placed in oscillator, revolving speed 150rpm, temperature is 25 DEG C, reaction time 240min；
4 data of table are obtained through detection.
4 charcoal preparation temperature of table activates the case where permonosulphuric acid potassium degradation 1,4-D to it
Table 4 the result shows that, charcoal preparation temperature it is activated permonosulphuric acid potassium degradation Isosorbide-5-Nitrae-D influence it is significant.With
The raising of charcoal preparation temperature, charcoal/permonosulphuric acid potassium system the removal efficiency of Isosorbide-5-Nitrae-D is gradually increased.Wherein, when
When charcoal preparation temperature is 800 DEG C, the removal of P800/ permonosulphuric acid potassium system and E800/ permonosulphuric acid potassium system to Isosorbide-5-Nitrae-D
Rate is respectively up to 84.2% and 85.2%.
Embodiment 5
The present embodiment is reused 3 times using Isosorbide-5-Nitrae-D in a kind of charcoal/permonosulphuric acid potassium system efficient degradation water
Charcoal/permonosulphuric acid potassium is compared the degradation efficiency of 1,4-D.It is raw to weigh the pine needle that 20.0mg preparation temperature is 700 DEG C
Object charcoal P700 and Eichhornia crassipes charcoal E700 are respectively placed in borosilicate glass bottle of the 22.0mL with screw lid；Step 2,
The water of-the D of Isosorbide-5-Nitrae containing 1.76mg/L and the permonosulphuric acid potassium of 8.0mmol/L are added in above-mentioned 22.0mL borosilicate glass bottle, just
Beginning pH is 6.5；Rapid three, above-mentioned borosilicate glass bottle is placed in oscillator, revolving speed 150rpm, temperature is 25 DEG C, reaction
Time 240min.Step 4 filters after first set reaction, removes supernatant, charcoal is dried and repeats step 1 and is arrived
Step 4.
Table 5 is in triplicate using charcoal to the degradation situation of 1,4-D
Table 5 the result shows that, two kinds of charcoals reuse three times after with permonosulphuric acid potassium coexist when, still have centainly
Activation permonosulphuric acid potassium degradation Isosorbide-5-Nitrae-D ability, this explanation, the present invention prepared by charcoal have more activated sites
Point.
It is schematically described above for the invention and embodiments thereof, description is not limiting.Institute
In the case where not departing from this creation objective, not inventively to set if those of ordinary skill in the art are inspired by it
Meter should all belong to protection scope of the present invention for the similar frame mode of the technical solution and embodiment.
