Abstract
Bioadsorption is an effective low cost tool for cleaning polluted environment. In the present study the seedlings of Vigna mungo (L) Hepper were treated with various concentrations of cobalt chloride and their impact on the growth, biochemical and enzyme characters were studied. After fourteen days treatment with different concentration of nickel chloride (2 mM, 4 mM, 6 mM, 8 mM and 10 mM) the growth parameter such as, shoot and root lengths, leaf area, fresh weight and dry weight were decreased than the control. Biochemical parameters such as chlorophyll, carotenoids, soluble sugar, and protein content and nitrate reductase activity also decreased with the increase in the concentration of cobalt chloride. But the content of free amino acid, proline, phenol and leaf nitrate content were increased with the increase in the concentration of cobalt chloride. The activities of enzyme such as catalase, peroxidase and polyphenol oxidase were found to be increased with the increase in the concentration of nickel chloride. Application of seaweed (Sargassum wightii) in different concentrations (2 gm/L, 4 gm/L and 6 gm/L) on 6 mM nickel chloride treated plants has shown the stress relieving effect caused by cobalt chloride. It is good low cost bioadsorbant for cobalt chloride.
