Title:
IRON-CONTAINING COMPOSITE REAGENT IN SUSPENSION LIQUID STATE, PREPARATION METHOD THEREFOR AND METHOD FOR EFFICIENTLY REMOVING SELENATE FROM WATER
Document Type and Number:
WIPO Patent Application WO/2018/090742
Kind Code:
A1
Abstract:
Disclosed is a preparation method for a suspension liquid-state iron-containing composite reagent. The steps are: (1) diluting a hydrogen peroxide solution; (2) adjusting the pH value of the diluted hydrogen peroxide solution with hydrochloric acid; and (3) adding a zero-valent iron powder for a reaction, so as to obtain the suspension liquid-state iron-containing composite reagent, wherein the molar ratio of hydrogen peroxide to zero-valent iron is between 0.2 and 0.8. Also disclosed are an iron-containing composite reagent in a suspension liquid state and a method for removing selenate from water.
