采用静态吸附法研究了330阴离子交换树脂对水中草甘膦的吸附性能,并研究了吸附动力学;测定了溶液的pH值、温度、NaCl含量等因素对330树脂吸附草甘膦的影响。结果表明:330树脂对水中草甘膦的吸附速率快;在pH=2.69时对草甘膦的吸附性能最好;330树脂对草甘膦的吸附是放热、自发的过程,吸附等温线符合Freundlich方程;NaCl含量对330树脂吸附草甘膦有显著影响。

The objective of this work was to study the adsorption properties of glyphosate onto 330 anion exchange resin by static adsorption.The adsorption kinetics of glyphosate onto 330 resin was measured.The study focused on the effects of the solution pH,temperature and NaCl on the adsorption of glyphosate onto 330 resin.The results showed that adsorption rate of glyphosate onto 330 resin was fast.The adsorption at the solution pH of 2.69 was the most efficient for 330 resin.Heat was discharged during the adsorption and the adsorption occurred automa...
