| Abstract: | A study on the sorption of monocrotophos and parathion methyl on Yellow River's sediments was performed. The influence of some factors, such as pH value and ionic strength, on the sorption was investigated and first order kinetics mode for the sorption of monocrophos was shown. Freundlich isotherm was suggested as the most appropriate type for monocrophos and parathion methyl. But the sorption isotherms of monocrotophos and parathion methyl are also in conformity with Langmuir equation. Both partition and adsorption occur to the sorption of monocrophos to Yellow River's sediments, but partition is the predominant for that of parathion methyl. |
