CATION EXCHANGE DISTRIBUTION BEHAVIOR OF SOME ELEMENTS IN AMMONIUM SULFAMATE-AQUEOUS-DIOXAN MEDIA ON TULSION T – 42H ORGANIC CATION EXCHANGER

Document Type : Original Article

Abstract

Ion Exchange distribution coefficient Kd-values have been measured for the partition of some metal ions, between Tulsion T–42 NH4 - form and a media which contain organic - aqueous - Sulfamate systems. A decreasing behavior of the distribution coefficients with the increase of sulfamate solution has been observed. The influence of change of the dielectric constant (DC) of the sorption medium has been also evaluated by using 10%, 20%, 30% and 40% (v/v) of the dioxan solution. Based on the calculated Kd - values obtained from the experimental data, several useful separations have been suggested and investigated for some binary systems under study.
