To remove glyphosate from water, nanosized copper hydroxide modified resin (D201Cu) was synthesized and characterized. The influence of NaCl concentration, temperature, pH, time, humid acid, and fulvic acid on glyphosate adsorption onto D201Cu resins were fully investigated. Glyphosate uptake on D201Cu was 113.7 mg/g in the presence 18% NaCl. The adsorption isotherms and kinetic data fitted well to the Langmuir model and pseudo-second-order model, respectively. In NaOH and NaCl mixed solution, the D201Cu regeneration efficiency can be 90% after five cycles. On the basis of the adsorption results, the schematic diagrams of adsorption mechanism of glyphosate onto D201Cu resins were proposed.
