Abstract
A new inorganic ion exchanger, zirconium–bis(triethylamine) has been synthesized. The material has been studied for its anion exchange capacity, sorption capacity, Kd values, composition, infrared spectrum and thermodynamic behavior. Analytically important separation of anions have been achieved. Ion exchange equilibria of Cr2O72−, CrO42−, SO42−, S2O32−, and MnO4− systems have been studied at 30, 40, 45, and 60 °C. The exchange isotherms have been measured for both forward and backward reactions with solutions of ionic strength 0.10 by batch process. The isotherms showed S shaped curves. The overall thermodynamic data are also calculated.Keywords
