[Sorption behavior of aldicarb on suspended particulate matter in water].
Batch adsorption experiments of carbamate pesticide aldicarb on suspended particulate matter(SPM) in water were carried out in this paper. The results showed that under 25 +/- 1 degrees C, at the aldicarb concentration of 0.2 to 1.5 mg/L, the adsorption of aldicarb on SPM followed Langmuir isotherm. At the range of 2.0 to 15 mg/L, the adsorption followed Freundlich isotherm. And at high concentration of 20 to 2000 mg/L the adsorption can be described using both Freundlich and Linear isotherms. Factors such as SDBS, TWEEN60, concentration of SPM, humic substances, pH, salinity, and microorganism affecting the sorption behaviors were also studied.
