Hydrous iron oxide and hydrous aluminum oxide were loaded successfully onto a polymeric adsorbent (D301) to modify adsorbingmaterials (HIOD301 andHAOD301). The adsorptive equilibriumof atrazinewas investigated in an aquatic environment using HIOD301 and HAOD301 under different experimental conditions. The results indicated that both HIOD301 and HAOD301 showed good adsorption capacities for atrazine at pH 4. The Langmuir and Freundlich isotherm equations were used to study the interactions between the adsorbate and adsorbent. The adsorption kinetics of atrazine at different concentrations was well described in terms of a pseudosecond- order equation in regard to the correlation coefficients and adsorption capacity. The removal percentages of atrazine for HIOD301 and HAOD301 were still more than 95% in the presence of sodium chloride.
