| Abstract: | The adsorption of Cu2+-laden wastewater with wheat straw was investigated.By means of equilibrium adsorption approach,the influence of experiment were carried out by considering additive amount of wheat straw,pH-value of solution,and reaction time on adsorptive capacity of Cu2+ in the solution by using wheat straw.The results showed that the adsorption was remarkably affected by the pH-value.The kinetics of the reaction exhibited better agreement with the Lagergren quasi-second-order kinetic model and the a... |
