- W2389030612 abstract "The adsorptive behavior of Pb2+and Cu2+ by humus was investigated. The result showed that the humus had a high adsorptive ability for Pb2+and Cu2+ but there were significant difference. The humus has a much higher adsorptive ability on Pb2+than on Cu2+.The adsorption isotherms of Cu2+ conform to Langmuir-equation was better than Freundlich-equation, but of Pb2+ both was well. According to the langmuir model, the maximum adsorption amount of Pb2+and Cu2+was 84.15 mg/g and 13.09 mg/g respectively. The former was 6.4 times of the latter.The pH value was the main factor affecting adsorption,humus at higher pH had a larger adsorption ability. The analysis of IR spectrum indicated that adsorption of Pb2+and Cu2+by humus caused the combination of carboxyl groups and hydroxy with heavy metal." @default.
