Synthesis and characterization of zirconium titanium phosphate and its application in separation of metal ions

“…The high selectivity of Pb 2+ is also observed in other TMA salts, viz., titanium molybdate (1000), titanium tungstate (1565), niobium arsenate (2980), antimony molybdate (800), antimony tungstate (145), zirconium phosphate (3800), titanium phosphate (2300), polyacrylonitrile thorium phosphate (800), zirconium tungstoiodophosphate (8500), titanium arsenophoshate (9500), antimony molybdotungstate (428), values in parenthesis is K d in mL g −1 [4,5,[23][24][25][26][27][28][29]. In case of Cu 2+ , other TMA salts exhibit only moderate or poor selectivity viz.…”

“…In case of Cu 2+ , other TMA salts exhibit only moderate or poor selectivity viz. zirconium phosphate (250), titanium phosphate (163), titanium molybdate (12), antimony molybdate (212), antimony tungstate (45), polyacrylonitrile thorium phosphate (80), antimony molybdotungstate (62), zirconium arsenophoshate (804), titanium arsenophoshate (131), zirconium tungstoiodophosphate (7900), values in parenthesis is in mL g −1 [4,5,[23][24][25][26][27][28][29]]. An extremely high affinity of Pb 2+ and Cu 2+ towards ZTP in the present study suggests its possible use for separation from other pollutants.…”
