Abstract
Phosphate sorption on the strong basic anion exchanger Amberlite IRA-400(Cl−form)is studied as a function of pH(3-11)and different initial concentration ranges (5-25 ppm,120-190 ppm)at 25°C. The ratio of chloride released /phosphate sorbed increases with the increase in pH and decrease with the increase in the concentration of the solution. It is suggested that phosphate sorption takes place initially as HPO2− 4 followed by H2PO− 4. The data is explained with the help of Langmuir and mass law action equations.This publication has 9 references indexed in Scilit:
