Studies on tetracycline hydrochloride sorbed zirconium tungstophosphate; La(III)-selective chelating ion exchanger

Tetracyclines are powerful chelating agents. One of its salt tetracycline hydrochloride has been sorbed over zirconium tungstophosphate (ZWP) and the studies of tetracycline-sorbed zirconium tungstophosphate (TCZWP) has been carried our as a chelating ion exchanger. The sorption of tetracycline has been supported by IR and its distribution studies on 17 metal ions have been calculated in DMW, 1 x 10(-5) M HNO3, 1 x 10(-3) M HNO3, 1 x 10(-2) M NH4NO3 and 1 x 10(-2) M NH4NO3 in 1 x 10(-5) M HNO3. On account of Kd values it was found selective for lanthanum(III) and separations from others have been successfully achieved on its column.
