Titanium(IV) tungstosilicate and titanium(IV) tungstophosphate: two new inorganic ion exchangers

摘要: Crystalline phases of Ti(IV) tungstosilicate and tungstophosphate have been synthesised. The ion-exchange capacities reported as 0.44 0.80 mequiv./g, respectively. Both materials show monofunctional characteristic are stable in 0.1 M solutions HNO3, HCl, H2SO4 acetone benzene. is found to be more thermally than (loss capacity was 58 80%, respectively for samples heated at 200 degrees C). Kd values heavy metals such Pb, Hg, Cd, Sb, Co, Zn, Ni, Fe, Cr etc. demineralised water two surfactant media by batch processes. Cr3+, Fe3+ Sn4+ totally adsorbed on both the while a decrease value with increase concentration surfactants reported. On basis metal ions, thirteen binary separations five ternary different four achieved. Separation methylamine from ethylamine has done GC column packed tungstophosphate.
