1. INTRODUCTION
Humic acid （HA） and Phytic acid （PA） are present in environment as a result of the decomposition of plant biomass, they are the major components of natural dissolved organic matter （DOM） in natural systems. It is now generally believed that these potentially carcinogenic chlorinated hydrocarbons such as THMs can be formed in the presence of these acids during the disinfection, which can cause liver, kidney or central nervous system problems . In order to reduce the formation of THMs, it is necessary to remove these substances as much as possible prior to chlorination. The aim of the present paper is tO Study the adsorption of HA and PA using different resins. Furthermore, the effect of HA molecular weight （MW） on adsorption are performed, and the adsorption of HA on different non-polar resins are investigated to elucidate the relationship between resin pore diameter and critical molecular size of HA adsorbed. Finally, the capacity of the bi-function resin WJN-10 to adsorb these acids in the presence of Pb（ II ） is investigated.
