Effectiveness Test of Hybrid Membranes Prepared of Polyamide 6 and Zeolite Y in Water Treatment

Abstract

The effectiveness of hybrid membrane of polyamide 6 and zeolite Y was examined in  the removal of salts of calcium chloride, magnesium chloride, sodium chloride, iron chloride  and Methylene Blue Dye from synthetic aqueous solutions, the membrane selectivity of cations Ca²⁺,Mg²⁺,Na⁺  and the effect of accompanying anion on removal efficacy were studiedr. pure water flow, salt retention ratio and its permeability coefficient were set.The results show the success of hybrid membrane (PA6/Z-4%) on polyamide membrane in the retention of the studied salts, The ratio of retention from salt to salt varies depending on the size and charge of the cation decreasing in orderCa²⁺> Mg²⁺> Na⁺ as it relates to the anion facilities are increased in order Ca(NO₃)₂>Ca(CH₃COO)₂> CaCl₂. Ion exchange capacity for hybrid membrane (PA6/4%ZY) 11.03 mg/g measured for calcium cation and 4.32 mg/g for magnesium cation, it is higher than the ion exchange capacity of the PA6 membrane measured for both ion.
