| Abstract: | 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 adsorpt... |
