Abstract

The objective of the present study was to investigate the removal of nickel (II) by foundry sand. The scope of work included batch mode adsorption, column mode removal and isotherm studies. Basically, batch adsorption study depended on various parameters like optimum time, dosage, pH, particle size and speed. Maximum removal of 29.07% nickel was achieved at 60 min contact time, dosage of 7g, pH 7, and particle size of 500 micron and speed of 100rpm. The Langmuir and Freundlichi sotherm study showed favourable condition for adsorption. The use of column adsorption study was investigated at optimum condition to study the feasibility for application in small scale industries. This column adsorption study showed that the results of flow rate of 15 ml 24 hrs-1 and bed height of 1cm were feasible. The breakthrough curves were constructed for various ratios of adsorbents. The percentage removal of Ni in clay adsorbent, clay with foundry sand (1:20), clay with foundry sand (1:10), and clay with foundry sand (1:5) were found to be 68.11%, 59.28%, 54.28 and 48.30% respectively.
