| 摘 要： | 研究废弃巴旦木壳对模拟废水中Pb、Cu和Cd的去除率。在单因素试验的基础上,采用响应面法对吸附剂投加量、吸附时间和pH值3因素进行优化。实验结果表明,最佳吸附条件为Pb：为吸附剂投加量0.4g、吸附时间49.38min、pH值为9.96；Cu：吸附剂投加量0.4g、吸附时间49.91min、pH值为10.13；Cd：吸附剂投加量0.4g、吸附时间49.83min、pH值为10.42；在此条件下,Pb、Cu和Cd的去除率分别为87.42%、73.49%和85.11%。采用偏最小二乘法(PLS)对Pb、Cu和Cd模拟混合试样吸附后的溶液进行同时测定,计算得出吸附剂对Pb、Cu和Cd的去除率分别为83.2%、66.0%和83.3%。

| Abstract: | Study the removal rate of Pb, Cu and Cd in simulated wastewater by discarded almond wood shells.On the basis of the single factor test, the response surface method was used to optimize the three factors of adsorbent dosage, adsorption time and pH value.The experimental results show that the best adsorption conditions are Pb: the adsorbent dosage is 0.4g, the adsorption time is 49.38min, and the pH is 9.96; Cu: the adsorbent dosage is 0.4g, the adsorption time is 49.91min, and the pH is 10.13; Cd: The adsorbent dosage is 0.4g, the adsorption time is |
