A New Rapid Determination Method of Soil Organic Carbon Adsorption Coefficients of Pesticides with Soil Column Liquid Chromatography

Dalian Institute of Chemical Physics, Chinese Academy of Sciences, Dalian 116011

Received Date: 15 August 2000

Soil column liquid chromatography (SCLC) was developed to determine soil organic carbon adsorption coefficients (K_oc) for chemicals. The uptake by soil of pesticides from water can be conveniently calculated from the related breakthrough curves (BTC). The nine pesticides chosen for determination in this study are soluble ones, with their water solubility ranging from 62 mg/L to 2 mg/L. In comparing with existing methods of K_oc, SCLC possesses rapid, online and accurate characteristics.
