  Removal and Recovery of Zn (II) from Electroplating Rinse Waters Using Cation-Exchange Resins in a Packed Column

  By Ajay Kumar Konga

  Abstract: In the present study, adsorption of Zn (II) ion from rinse water of electroplating Zinc has been attempted by Indion 225 and Dueolite C20 cation exchange resins through batch and column mode. Based on isotherm analysis more efficient adsorbent is chosen for column mode adsorption studies. Indion 225 and Dueolite C20 cation exchange resins showed a remarkable increase in sorption capacity as 49.3mg/g and 13.9mg/g for Zn (II) ions respectively …

  Continuous Column Study of Chromium (VI) Adsorption by Ion Exchange Resin

  By Ajay Kumar Konga, Gomathi Priya Ponnaiah

  Abstract: The Indion GS300 anion exchange resin was trialed for its ability to remove chromium (VI) from synthetic wastewater by continuous column experiments. The ability of Indion GS300 to adsorb chromium (VI) in a fixed-bed column was analyzed. The effects of operating parameters such as flow rate and bed depth on the sorption characteristics of Indion GS300 were investigated. The total adsorbed quantities, equilibrium characteristics were related to the effluent volumes …
