AI Technical Summary

Technical Problem

The inorganic anions introduced during the synthesis of existing water treatment agents lead to a decrease in the molecular weight of the agents and secondary pollution, and the removal effect on fluoride ions is not good.

Method used

A sol is prepared by electrolyzing an ammonia solution with organic additives and hydrogen peroxide. The sol is then mixed with acrylamide and cationic monomers and polymerized. This process avoids the introduction of heterogeneous anions and improves the efficient in-situ polymerization of organic components on inorganic components, resulting in an agent with both defluorination and flocculation capabilities.

Benefits of technology

The prepared reagent avoids the initiation of anion-inhibited chain free radicals, increases the molecular weight of the reagent, and achieves efficient removal of fluoride ions and rapid sedimentation of suspended solids. It has excellent defluorination and flocculation performance and does not produce secondary pollution.
