| Abstract | HEEP COPYRIGHT: BIOL ABS. Removals of Ca, Cu, Cr, Ni, Pb and Zn from water and waste water samples by different concentrations of zeolite type A and with zeolite type A forms where Na was partially exchanged for Ca were determined. Metal concentrations were determined after a range of different treatments such as filtration, sedimentation in columns and centrifugation. Rate of removal of Ca hardness from samples was a function of Ca hardness present in samples. High concentrations of zeolite removed all metals except Cr from water, but only Pb, Zn and Cd from synthetic waste water samples. In water samples containing Cd, Ni, Cu and Zn, an increase in Ca exchanged for Na in zeolite resulted in a decrease in percentage of Ni removed from suspension on mixing. At lower environmental concentrations, zeolite type A had no effect on metal removal from raw waste water samples. |
