It is 35-45Hz, 800-1000W to state ultrasound condition, is rinsed 2-3 times using hydrochloric acid solution after taking-up, and distilled water immersion 3- is then used
5h, filtering drying to constant weight；
（2）By step（1）Gained activated carbon is added in 10-20 parts of pomelo peel extracting solutions, and revolving removes moisture, and by gains
It is put into vacuum drying chamber, dries 10-20h at 70-80 DEG C, obtain modified activated carbon；
Further, the preparation method of the modified activated carbon-polyaluminum ferric chloride composite particles is：By the modified activated carbon
It is sprayed using chitosan solution, after the one layer of spraying of surface uniform fold, gains is added to 5-10 parts of polyaluminum ferric chloride
It in solid, stirs evenly, makes its one layers of polymer aluminium chloride ferrum particle of surface adhesion, be subsequently placed into 40-50 DEG C of vacuum drying chamber
Middle dry 5-10h；
Further, step（1）The ethanol solution mass concentration is 70-80%, concentration of hydrochloric acid solution 5-10%, sodium hydroxide
Solution concentration is 5-10%.
Further, step（2）The preparation method of the pomelo peel extracting solution is：After pomelo peel is cleaned up, be put into-
In 40~-50 DEG C of household freezer, freezing 2-3h is carried out, is then taken out, crushed to grain size≤3mm, its volume 10-30 is added
It in distilled water again, is put into reaction kettle, is 60-70 DEG C in temperature, pressure is high pressure extraction 4-5h under 500-600MPa, so
After filter, by filtrate rotate remove 2/3-5/4 moisture, obtain pomelo peel extracting solution；
Further, the chitosan solution is chitosan acetic acid solution, and wherein chitosan content is 30-40%, and acetic acid content is
5-10%。
Beneficial effects of the present invention：Activated carbon is modified by the present invention by shaddock bark extract, the shaddock for keeping its absorption sufficient
Sub- bark extract recycles chitosan spraying one layers of polymer aluminium chloride ferrum powder of adherency, forms modified activated carbon-aluminium polychloride
Iron composite particles are greatly improved gained liquid detergent by being compounded with alkyl glycosides A, dodecanamide propyl amine oxide etc.
Powder to the removal ability of fruit and vegetable surfaces pesticide residue, and not harmful to human, do not destroy living environment, Nonpoisonous, non-environmental-pollution, be easy to
It rinses, is green safe；Activated carbon is modified using shaddock bark extract, abundant lemon in one side shaddock bark extract
Alkene has very strong dirt-removing power, and environmentally protective, pesticide residue ability is gone in the decontamination that liquid detergent can be improved, on the other hand, cooperation
The physical friction performance and physical adsorption property of activated carbon, decontamination go pesticide residue ability to greatly improve；It is sprayed using chitosan
Mist is wadded a quilt with cotton in modified activated carbon surface adhesion polyaluminum ferric chloride, the chemistry of the physical absorption and polyaluminum ferric chloride that can make activated carbon
Solidifying effect collaboration plays effect, is remarkably improved the remains of pesticide extraction efficiency of fruit and vegetable surfaces, is readily cleaned simultaneously, will not cause
Liquid detergent is in the secondary retained of fruit and vegetable surfaces, harm health；The extracting method extraction efficiency of pomelo peel of the present invention is high, gained extraction
Limonene content is higher in object.

Control group
Commercially available fruits and vegetables liquid detergent.
Experiment：
Pesticide residue removal effect is tested：This experiment is chosen romaine lettuce and is represented as fruits and vegetables, chooses chlopyrifos and is represented as pesticide, will
Pesticide aqueous solution, a concentration of 150 μ g/mL is made in chlopyrifos；A certain amount of romaine lettuce is weighed respectively to soak in above-mentioned the pesticide solution
30 min are steeped, then pulls out, dry in the shade, about 12 h are placed in 4 DEG C of refrigerations with after the freshness protection package packaging of food-grade.By each group sample
Then the solution that product add clear water to be diluted to 15g/L uses clear water with the romaine lettuce sample 15min with chlopyrifos of its immersion gained
Rinsing 3 times, dries in the shade.Then it by romaine lettuce sample after extraction and cleaning, is poisoned using high performance liquid chromatography detection romaine lettuce sample
The residual condition of dead tick, testing conditions are：Mobile phase is methanol/water (8: 2, V/V)；Flow velocity is 1.0 mL/min；Sampling volume
For 20 μ L；Detection wavelength 234nm, calculates removal rate, and testing result is as shown in table 1：
Table 1
| Chlopyrifos removal rate % | |
| Embodiment 1 | 99.99 |
| Embodiment 2 | 99.99 |
| Embodiment 3 | 99.99 |
| Comparative example 1 | 46.4 |
| Comparative example 2 | 52.8 |
| Comparative example 3 | 47.1 |
| Comparative example 4 | 10.5 |
| Control group | 70.6 |
As can be seen from Table 1, the concentration fruits and vegetables containing modified activated carbon-polyaluminum ferric chloride composite particles prepared by the present invention are washed
Clean fine powder, can completely remove the pesticide residue of fruit and vegetable surfaces, and removal rate is about 100%, hence it is evident that be more than the pesticide of commercially available liquid detergent
Removal rate（70.6%）, and it is green safe, it is worth promoting.
