Preparation method of leaching liquid for repairing heavy metal polluted soil

[0043] A kind of preparation method of the eluent of repairing heavy metal polluted soil, dioctyl sebacate, 4-(2,6,6-trimethyl-2-cycloocten-1-yl)-3-butene -2-ketone, 1,4-dimethylpiperazine, 2-pyridinemethanol, oleanal, salicin, 4-aminoisoquinoline, alkyl polyoxyethylene ether acetate were added to the stirring Add deionized water and polycarboxylates to the flask with a thermometer, a thermometer and a reflux condenser, raise the temperature to 850°C, pass through nitrogen protection, stir for 45-75min, then slowly add ammonium citrate dropwise, and the dropwise addition is completed in about 2 hours. After 2 hours of heat preservation, add sodium alginate, sodium ethoxide, polyoxypropylene glycol, and fatty alcohol polyoxyethylene ether, react for another 4-7 hours, and cool to room temperature to obtain the eluent for repairing heavy metal-contaminated soil;
