Abstract

Abstract: Adsorptions of humic acid(HA) and tanic acid(TA) on weakly basic resin(D-301) were investigated. The result indicates high molecular weight of humic acid can decrease resins adsorption capacity. Furthermore, resins adsorption capacity for humic acid is slightly higher in the presence of low concentration of phenol, but a decrease in resins adsorption capacity for humic acid is observed in the test when concentration of phenol is high. NaCl and pH also show an influence to resin's adsorption capacity.

Key words: Weakly basic resin, Humic acid, Adsorption
