| Abstract | ||
| This study was carried out at Agricultur College Lab./Tikrit University to evaluate Zn adsorption / desorption behavior under field conditions by using disturbed soil colums (4) soils different in Gypsum content , 5,8,14,18 % Gypsum .pattern of Zn adsorption and desorption were investigated by using four Kinetic model .first order ,second order ,third order and Elovich equations. Results showed that the dinemic equilibirium accured after 35 minutes and Zn adsorption was affected by soils clay and organic matter content,while Zn desorption affected by calcium carbonate and Gypsum content.Result also showed that first order and Elovich equations were that best fitted model describing Zinc adsorption and desorption in soils studied.which have highest correlation coefficient (R2) values ranged between "85-88 %" . | ||
