| 摘 要： | 目的]为砷污染地下水体的修复研究提供依据。方法]利用稻草秸秆作为吸附剂,研究稻秆长度、稻秆用量、pH值、干扰离子等因素对饮用水中五价砷去除的影响。结果]当五价砷浓度为300μg/L,稻草秸秆长度为2 mm,秸秆用量为10.0 g/100 ml溶液,最佳pH值中性,吸附时间为24 h时,稻草秸秆对五价砷的去除率可达99%以上,符合国家饮用水标准。结论]利用稻草秸秆去除饮用水中五价砷有一定的应用前景。

| Abstract: | Objective]The research aimed to provide references for the study of arsenic pollution groundwater restoration.Method] The influence of rice straw size,rice straw amount,pH value,interfering ions to the removal of pentavalent arsenic in drinking water was studied with rice straw as adsorbent.Results] The removal rate of pentavalent arsenic was 99% when the pentavalent arsenic content was 300 μg/L,the rice straw was 2 mm,the rice straw amount was 10.0 g/100 ml,the pH value was neutrality,adsorption time was 24 h.The water after treatment accorded with National Standard(GB) for Drinking Water.Conclusion] The method to remove pentavalent arsenic in drinking water with rice straw had specific application foreground. |
