ABSTRACT

 

Amberlite IRA-400 is a strongly basic anion exchanger resin. In the present work, Amberlite IRA-400 is modified with disodium salt of ethylene diamine tetra acetic acid (Na2EDTA). The modified chelating cation exchanger is characterized by various instrumental techniques like TGA, FTIR and EDX. The resultant cationic ion exchange is used for removal of Pb (II) from aqueous solution using batch method. Various parameters such as effect of concentration, equilibrium time and effect of pH have been varied in order to get maximum removal of Pb (II) ions. Further sorption of Pb (II) ion on chelating ion exchange was confirmed by EDX. Ammonium nitrate, nitric acid, perchloric acid and acetic acid were tested as eluants. The studies indicate that promising use of modified chelating ion exchange for selective removal of Pb (II).
