Abstract

Nano-iron and copper oxides loaded weakly basic resin D301 was investigated for the removal of glyphosate from aqueous solution. The characteristics of the resin before and after surfactant-modification were examined using scanning electron microscopy and Fourier transform infrared spectroscopy. The effects of pH, contact time, temperature and coexisting humic acid and fulvic acid were studied by batch adsorption. Adsorption of glyphosate was found strongly affected by the pH, with pH 3 providing maximum adsorption of glyphosate from aqueous solutions. The pseudo-first-order rate and pseudo-second-order rate models were applied to the experimental data. Glyphosate adsorption clearly followed the pseudo-second-order model. Moreover, fulvic acid had obvious effect on glyphosate adsorption.
