摘要: The convenient and feasible pretreatment method of alkali treatment is very common in the degradation process wheat straw. However, its utilization straw as alternative adsorbents for aqueous heavy metals remediation rarely reported. present study investigated removal efficiency Cu(II) ions using with pretreatment. condition on was optimized adsorption capacity indicator single-factor experiments. influences dosages, pH values, contact time, temperatures performance both untreated (UWS) alkali-treated (AWS) were investigated. Results showed that relatively large rate could be obtained, chemical behavior occurred during process. Characteristic analysis found major function to introduce hydroxy group, which resulted increase -C-O- group. Although not high one ligands supported adsorbents, easy operate has a wide range application; at same it realize purposes treating metal pollution solid wastes.
