【Abstract】 A new composite material consisting of nano-molecular sieve and diatomite was used to statically treat wastewater containing copper.The crystal form of diatomite matched with molecular sieve,optimum mixture ratio and total use quantity was optimized through the orthogonal experiment.The adsorption equilibrium and the dynamic data of copper ion on the composite material were determined.The adsorption equilibrium conformed to the Freundlich equation and the model pa- rameters were obtained.The results show that the Freundlich model can describe the system’s characteristics.更多还原
