Abstract

The present invention relates to a kind of preparation methods of vegetable residual pesticide cleanser, belong to cleanser technical field.Technical solution of the present invention uses plant ash and heavy salinized leaches material as raw material, high alkalinity environment is provided by leachate, since plant ash main component is potassium oxide, by being dispersed and under alkaline environment, under the action of metal ion, it decomposes organophosphorus pesticide effectively and forms phosphoric acid species and alcohols material, effectively decompose and remove vegetables and fruits farm chemical ingredients remained on surface;Technical solution of the present invention also uses hydrogen peroxide and silica solution to be used in combination, since hydrogen peroxide has efficient oxidation susceptibility, it can be effectively with organophosphorus pesticide oxidation reaction and degrading organic phosphor pesticides remain, simultaneously, technical solution of the present invention uses coagulant liquid as load carriers, cleanser ingredient is effectively improved in the adhesion property and adsorption effect on vegetables and fruits surface, plays higher absorption property and higher degradation effect.

Description

A kind of preparation method of vegetable residual pesticide cleanser
Technical field
The present invention relates to a kind of preparation methods of vegetable residual pesticide cleanser, belong to cleanser technical field.
Background technique
The living standard of people is improved constantly, therefore increasingly pays attention to environmental protection and food-safety problem.In these problems In with people it is closest be exactly the exceeded problem of remains of pesticide amount in agricultural product, the exceeded problem of remains of pesticide amount is direct Affect the health of people.Therefore many scholars of recent domestic utilize ozone degradation method, microbial degradation method, work Property enzyme disintoxication, ultrasound involve the different method such as ultraviolet light the remains of pesticide problem in agricultural product studied.But These methods are inconvenient to use, and cost is also relatively high.Mainly use clear water or detergent in people's daily life at present The methods of washing by soaking vegetables, the former cannot completely remove remains of pesticide, and inherently a kind of chemicals of the latter, also can be right Human health affects.Therefore a kind of easy to operate, nonhazardous, removal vegetable residual pesticide at low cost are studied Method has great meaning to people's health.
Vegetable residual pesticide not only seriously affects human health, but also influences agricultural development and international trade.Many pesticides The generation of accident, such as drops in production over a large area, and is all to have seriously affected agricultural development because unreasonable using pesticide.Due to WTO/SPS Agreement joined the detection of the persticide residue of vegetables and become developed country's control technical barrier to trade, become One of the means of developed country's control trade.China is the big country of an export of farm produce, and at this stage for the agriculture in vegetables Medicine residual quantity control means be not also it is as sound as a bell, be restricted in exit procedure so causing many agricultural product, very The limit amount that more persticide residues cannot reach international is horizontal, and very big shadow is also caused to the International Agricultural Trade in China It rings.
The washing methods of vegetable pesticide residue has very much, has physical method, chemical method and microbial degradation by chemical property point The fairly simple some sides of storage, originally washing, boiling water boiling, peeling etc. are commonly used in method three categories, people in daily life Method.There are also some methods that can remove vegetable residual pesticide, such as salt and vinegar are added in water or uses detergent, furthermore Vegetable residual pesticide can also be removed there are also some instruments.It is directed to different vegetable varieties in these methods, washing vegetables are residual The method for staying pesticide is also different, and if decortication method is not suitable for leaf vegetables, only applicable use can be with long-term storage for storage method Vegetables etc..
Summary of the invention
The technical problems to be solved by the invention:For the problem that existing cleanser absorption property is poor, one kind is provided The preparation method of vegetable residual pesticide cleanser.
In order to solve the above technical problems, the technical solution adopted by the present invention is that:
A kind of preparation method of vegetable residual pesticide cleanser, specific preparation step are:
(1)It takes heavy salinized ground soil and grinds, pulverized particles of being sieved to obtain take plant ash and in mass ratio 1:1, by vegetation Ash is stirred and regrinds with pulverized particles, is sieved and collects sieving powder;
(2)In mass ratio 1:10, sieving powder and deionized water are stirred and heating water bath, standing, centrifugation are collected respectively Supernatant liquor and lower sediment must leach modification liquid and sediment respectively, and sediment vacuum freeze drying is obtained dried object;
(3)It takes triangle pearl freshwater mussel clam shell and is crushed to obtain clam shell particle, in mass ratio 1:1, dried object and clam shell particle are stirred mixed After be placed in grinding distribution in mortar, collect disperse materials and be placed in crucible, preheating, heating heating, heat preservation calcining stands It is cooled to room temperature, is ground up, sieved, obtain calcined powder;
(4)In mass ratio 1:10, calcined powder is added in deionized water, 1~2h is stirred and stands, filters and collects Filter cake, after dry, standing is cooled to room temperature, and obtains calcining modified materials;
(5)According to parts by weight, 45~50 parts of leaching modification liquids, 15~20 parts of silica solution, 15~20 parts of peroxidating are weighed respectively Hydrogen solution and 10~15 parts of calcining modified materials are placed in a beaker, and are stirred to obtain coagulant liquid, and it is residual can be prepared into the vegetables Stay pesticide cleanser.
Step(3)The calcined temperature is 100~110 DEG C.
Step(3)The heating, which is heated to be, is warming up to 950~1000 DEG C by 8 DEG C/min.
Step(5)The silica solution is the silica solution that Baume degrees is 15.
The present invention is compared with other methods, and advantageous effects are:
(1)Technical solution of the present invention use plant ash and it is heavy salinized leach material as raw material, provided by leachate high-alkali Property environment, due to plant ash main component be potassium oxide, by being dispersed and under alkaline environment, the effect through metal ion Under, it decomposes organophosphorus pesticide effectively and forms phosphoric acid species and alcohols material, effectively decompose and remove vegetables and fruits remained on surface Farm chemical ingredients;
(2)Technical solution of the present invention also uses hydrogen peroxide and silica solution to be used in combination, since hydrogen peroxide has efficient oxygen Change performance, can effectively with organophosphorus pesticide oxidation reaction and degrading organic phosphor pesticides remain, meanwhile, technical solution of the present invention uses Coagulant liquid effectively improves cleanser ingredient in the adhesion property and adsorption effect on vegetables and fruits surface, plays as load carriers Higher absorption property and higher degradation effect.
