| Abstract: | This work investigated the adsorption behaviors of Cu2+ in wasterwater on alkali treated wheat straw and applying prospect of modified wheat straw in wasterwater treatment were also presented.Some conditions that affected the adsorption capacity of Cu2+ such as adsorbent dose,pH and agitation time were investigated.Simultaneously,the change of product apparent morphology and crystal structure were analyzed by XRD and SEM. |
