PROCESS FOR THE PREPARATION OF SYNTHETIC HUMIC ACIDS AND USE THEREOF IN SYNTHESIS OF SILVER NANOPARTICLES

摘要

A process for the preparation of synthetic humic acids is characterized in that the reaction of polycondensation of pyrocatechin with hexamethylenetetramine is used for synthesis. The polycondensation product is amphoteric resin and capable of reducing silver ions with formation of solution containing nanoparticles of metallic silver stabilized with synthetic humic acids.
