ADSORPTION OF TANNIC ACID BY HYPER-CROSSLINKED RESIN MODIFIED BY AMINO FUNCTION GROUPS
氨基修饰超高交联树脂对单宁酸的吸附行为及机理研究

Tannic acid(TA) as a typical natural organic acid of high solubility and medium molecular weight,was used to study the adsorption act and mechanism on a new hyper-crosslinked resin modified by amino function groups WJN-08.The adsorption isotherm data indicates that the equllibrium adsorption capacity of WJN-08 for TA is 15% higher than that of other commercial adsorbents.Moreover,the static adsorption assay indicates that the adsorption capacity for TA is related to the pore structure and the amounts of ami...
