Abstract：To investigate the secondary formation of chloroform under the influence of colloidal effect during managed aquifer recharge, this paper used batch experiments to study the formation of chloroform under different hydrochemical conditions with and without colloids. The synergistic mode between chloroform and silica colloids was analyzed by tangential flow ultrafiltration technique combined with atomic force electron microscopy(AFM). The results indicated that the formation of chloroform increased with the increase of contact time. High chloride/TOC ratios, high pH, and low ionic strength promoted the formation of chloroform in a specific contact time. The presence of silica colloid affected the adsorption of the reaction precursor, which inhibited the formation of chloroform at all contact times and had a strong adsorption effect on chloroform in water. These results can provide a scientific understanding of the secondary formation of chloroform during artificial recharging processes.
