[0030] A kind of preparation technology of solid heavy metal-removing propolis, concrete steps are as follows;
[0031] 1) Pretreatment: Grind propolis raw materials at -3°C to 100 meshes to obtain propolis powder, dissolve propolis powder in deionized water 5 times its mass, heat to 60°C, cool to 0°C and let stand. Removal of solids to obtain a pretreatment solution;
[0032] 2) Removal of heavy metals: Add the pretreatment solution obtained in step 1) to a mixture of propylene glycol alginate and polyoxyethylene sorbitan monolaurate at a mass ratio of 2:0.3, which is 0.01 times the mass of propolis powder, and stir evenly Finally, add a zeolite-based heavy metal adsorbent equal in quality to the propolis powder, stir for 30 min, let stand for 0.5 h, and filter to remove the solid to obtain a propolis solution;
[0033] 3) Preparation of solid heavy metal-removing propolis: dissolve the propolis solution obtained in step 2) in an aqueous ethanol solution with a mass fraction...
