Modelling of Reaction Kinetics of Lead in Contaminated Soils of Coimbatore District of Tamil Nadu, India
Subscribe/Renew Journal
The knowledge of kinetics of reaction is critically important for sound prediction of likely outcomes of remediation of contaminated soil. However, there is little information available on the sorption of Pb in soils receiving electroplating effluents and sewage water irrigated practices rich in Pb and other metals. Hence, this experiment was carried out to find out the Pb kinetics behaviour of contaminated soils of various soil types. Detailed investigations were carried out on the modeling on reaction kinetics of Pb in soils of contrasting character found in polluted soils of study area. The results revealed that, Pb required 22 hours to reach equilibrium for all soils irrespective of soil types and fitted well to zero order and second order kinetic equations for six soils under studied than did for first order, third order and parabolic equations.
