摘要

Tannic acid and its related compounds are known as refractory organic pollutants

and it can create serious problems for the environment. The adsorption and desorption studies of tannic acid on commercial resins XAD-7 and D-201 are performed

and all data indicates resin XAD-7 can be used as an effective adsorbent for removing tannic acid during water/wastewater treatment. Furthermore

adsorption thermodynamics studies indicate different adsorption mechanisms for TA on XAD-7 and D-201. FT-IR and solid state 13C-NMR spectroscopy are used to explain the adsorption force between XAD-7 and TA. It suggests that hydrogen bonding is the main adsorption force for TA. Finally

XAD-7’s adsorption capacity in the presence of different metal ions is investigated

which indicates that heavy metal ions in solutions can decrease the adsorption capacity for TA on ester resin XAD-7.
