Abstract:

Heavy metals are highly toxic and non-biodegradable and their accumulation in the living tissues can cause various diseases and disorders. Hence there is a need to remove these metal ions from the wastewaters from industries before discharging into the environment. In the present paper removal of Ni(II) by esterified (Tectona grandis) saw dust by sequential bed and vertical columns have been investigated. Column studies have been carried out at optimum pH and particle size and the effect of flow rate and metal ion concentration have been investigated using sequential bed as well as vertical columns. Thomas model and Yoon-Nelson model were used to evaluate model parameters and predict the adsorption performance and capacity in a fixed-bed column. The bed capacity qo for sequential column is more than a vertical column at a flow rate of 1.2 l/hr and influent concentration of 200 mg/l. It is found that breakthrough time for sequential column is more than vertical column.
