摘要：

Comparative adsorption of glyphosate from aqueous solution by 2-aminopyridine modified polystyrene resin (denoted GQ-08 resin), D301 resin and 330 resin was investigated with respect to influencing factors, salinity resistance and mechanism. Results showed the maximum adsorption capacity of glyphosate onto the three resins was observed at pH of 2.51, and glyphosate was adsorbed in the form of HOPO2-CH2NH2+CH2COOH and HOPO2-CH2NH2+CH2COO-. The adsorption capacity of glyphosate onto the three resins followed the order 330 resin >D301 resin >GQ-08 resin, consistent with their total exchange...
