Department of Chemistry and Environmental Engineering, Hubei Normal University, Huangshi 435002, China; 2. School of Resources and Environmental Engineering, Wuhan University of Technology , Wuhan 430070, China) Abstract: The preparation technological conditions and regenerat ion method of a novel granulated adsorbing material of fly ash and rectorite and the use of it to remove heavy metals from copper smelter industry wastewater were studied. The experi mental results showed that under the conditions of the ratio of rectorite and fly ash of 11, the amount of the additive( IS) of 15% , the amount of 50% water, and the calcination temperature of 500 , the efficiency of metal removal w ith the granulated materials was t he best, whereas the rat io of disi
