Abstract

The removal of Ni (II) from electroplating waste water have been studied by using chelating anion exchange resin Dowex M-4195. Adsorption was carried out in a batch process with different concentrations of Ni (II) ions by varying pH and agitation time. The uptake of the metal ion was very fast in initially, but gradually slowed down indicating penetration into the interior of the adsorbent particles. The adsorbent had a considerably high. Langmuir monolayer capacity of 300 mg/g. A small amount of the adsorbent (1 g/L) could remove as much as 87 % of Ni (II) in 300 min from a solution of concentration 5 mg/L at 300K. The adsorption continuously increased in the pH range of 2.0-4.0, beyond which the adsorption could not be carried out due to the precipitation of the metal ion. The experimental data closely followed both Langmuir and Frundlich isotherms.
