Heavy metals have a great tendency to bio-accumulate and end up as permanent additions to the environment. In this study, removal of Nickel from aqueous solutions has been investigated by utilizing a fly ash as an adsorbent. The Fly Ash has been collected from Kota Thermal Power Station (KTPS). Dimethylglyoxime (DMG) is used for the spectrometric determination of Nickel. Batch adsorption experiments were carried out to study the various parameters such as effect of initial metal ion concentration, effect of pH, adsorbent dose, and contact time.
