胺基螯合蔗渣纤维素对模拟废水中Cu2+的吸附
Absorption of Copper Ions by Amino Chelated Bagasse Cellulose in Simulated Heavy Metals Wastewater
摘要
Abstract
The effects of pH, temperature, absorption time and the initial concentration of Cu2 + on the absorption of Cu2 + by the amino chelated bagasse cellulose which was prepared in advance in simulated heavy metals wastewater were investigated. Experimental results showed that the adsorbance of Cu + by amino chelated bagasse cellulose increased with the increase of the value of pH or the initial concentration of Cu2 + . After 25 min of absorption, adsorption of Cu2 + almost was saturated. Study of absorption kinetics of Cu2 + indicated that amino chelated cellulose absorption of Cu + was in line with the Pseudo-second-order Kinetic model. The equilibrium data was tested with Langmuir and Freundlich isotherm equations. Langmuir isotherm was proved to be more suitable for the description of adsorption of Cu2+ by amino chelated bagasse cellulose.关键词
