Efficiency of Copper Removal from Wastewater with Zeolite/EPDM Composite
In our study, a new kind of material for Copper (Cu2+) absorbency was prepared by melt blending with EPDM as the matrix and modified zeolite as the filler. In order to overcome this obstruction, PEG-2000 was used as pore forming agent. By calculating, trial parameter n was 1.9, so, the composite was easy absorption. By SEM and XRD measurement, it was confirmed that the composite was more suitable as filler than the original zeolite and the acid modified zeolite. It can be showed that the pore forming agent adding was necessary and effective for the absorption by SEM micrograph of suction passage in EPDM and the composite.
