Effects of pH and organic matter on Cu adsorption in a sandy loam near orchard were studied.Results showed that i)the isotherm of Cu adsorption could be described by Freundlich equation and ii)statically adsorbed Cu was easier to get desorbed than specifically adsorbed one.Kinetic experiments demonstrated that up to 60% of the Cu adsorption occurred within the initial 4 h,and equilibrium was reached after 8 h,while up to 80% of the Cu desorption did within the initial 30 min, and equilibrium was reached after 2 h.Cu adsorption rate was lower at low pH than at higher pH,which was a result of competitive adsorption of H⁺,and logK_d showed a positive linear correlation with pH while in neutral and alkali condition,the effect of pH on adsorption could be neglected.The removal of organic matter from the soil reduced the distribution coefficient K_d 10 times as compared to the natural soil.
