| 摘 要： | 利用壳聚糖负载膨润土吸附处理含磷废水,考察了吸附剂投加量、吸附时间、振荡强度、pH值等对磷去除率的影响。结果表明:投加量为0.5g、吸附90min、振荡强度为100 r/min、pH值为7,25℃下对25mL质量浓度为2mg/L的磷溶液去除率为78.25%。壳聚糖负载膨润土对磷的吸附符合Langmuir等温吸附模式。

| Abstract: | The effects of adsorbent dosage,adsorption time,oscillation intensity,pH value on phosphorus removal by chitosan loading bentonite were studied.The results showed that: for initial phosphorus of 2 mg/L in 25mL,at the temperature of 25 ℃,the removal rate of phosphorus was 78.25%,when the adsorbent dosage was 0.5 g,adsorption time was 90 min,oscillation intensity was 100 r/min and pH value was 7.The phosphorus adsorption on chitosan loading bentonite conformed to Langmuir equation. |
