| Abstract: | The kinetics of anaerobic degradation of lindane in sediment from Liaohe River,Northeastern China,was investigated.Lindane displayed different anaerobic degradation characteristic under different organic mutrient conditions.The degradation rate was fitted for one order kinetics.The constants of degradation rates were 0.136d-1,0.51d-1 and 0.136d-1 respectively when glucose,sodium acetate and albumen were used as carbon resources,while the constant was 0.0487d-1 if no extra carbon resource was added.The main degradation product was detected to be dichlorobenzene using GC MS. |
