摘要

Gelatin-tin (IV) phosphate nanocomposite (GT/TPNC) ion exchanger was synthesized by mixing gelatin gel into the precipitates of tin (IV) phosphate using sol-gel method. GT/TPNC was characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The ion exchange capacity of GT/TPNC was reported to be1.44 meq/g. The material was found monofunctional as indicated from pH titration curves. The distribution coefficient of different metal ions such as Zn2+ (42.10), Cd2+ (37.93), Mg2+ (33.33), Cu2+ (33.21), Al3+ (14.28), Pb2+ (6.06), Ni2+ (12.50) and Co2+ (50.0) was studied using GT/TPNC ion exchanger. The distribution studies confirmed the selectivity of GT/TPNC for Co (II). The photocatalytical degradation of MB was found to be 78% within 5 h of solar illumination using GT/TPNC. Some binary separations such as Co2+-Pb2+, Cd2+-Ni2+, Co2+-Mg2+, Mg2+-Zn2+, Pb2+-Zn2+, Cu2+-Al3+, Al3+-Cd2+, Ni2+-Cu2+ were attempted using GT/TPNC ion exchanger. GT/TPNC was explored for the fabrication of ion-sensitive membrane electrode for the determination of Co (II) in the water system. The membrane electrode was found mechanically more stable with quick response time (30 s) and a wide pH working range (4.0-7.0). (C) 2018 The Society of Powder Technology Japan.
