改性沸石制备及对其铬吸附特性的研究
Preparation of Modified Zeolites and Their Adsorption Characteristics of Chromium
摘要
Abstract
In order to solve the low adsorption capacity of natural zeolites to heavy metals in wastewater, six kinds of modified zeolites were prepared and the adsorption properties of modified zeolites to hexavalent chromium ions were investigated. Among the six modified zeolites, H2 SO4/CuSO4 composite modified zeolite has the best adsorption performance to chromium. The adsorption curve of chromium is in accordance with Freundlich equation. Its adsorption intensity is 8 times that of natural zeolite. The adsorption kinetic curve accord with the second-order kinetics model. The results show that ion exchange plays an important role in the adsorption of hexavalent chrome ion, which is very close to the theoretical value.关键词
