Adsorption behavior of endosulfan on alluvial soil

The present study was carried out to assess the behavior of endosulfan pesticide in alluvial soil under laboratory conditions. sandy loam soil was studied to evaluate the fate of applied endosulfan with respect to soil properties. known amount of endosulfan was added on alluvial soil in pvc column and eluted with 1000 ml of water. eluents were collected in 10 parts,each of 100 ml. the soil in the column was divided in to three equal parts,each of 10 cm. each part of the soil and eluents were analyzed for the determination of endosulfan level using gc- μecd and gc-ms techniques. the kinetic and equilibrium adsorption characteristics of endosulfan on sandy loam soil was also studied and found that it follows ho's pseudo second order and freundlich isotherm. the present study revealed that α-and β-endosulfan was determined efficiently with their degraded products in alluvial soil under laboratory conditions with above mentioned instruments.
