摘　　要：研究了辣木籽活性成分提取的条件及提取液对模拟水样和实际水样的除浊效果。结果表明,NaCl作为提取剂对浊度的去除效果较好,且最佳NaCl浓度为0.25 mol/L;随着pH的升高,辣木提取液最佳投加量增加,且最佳pH范围为7~8;辣木提取液对中高浊度水的去除效果较好,对低浊度水的去除效果不好,但对实际低浊水的去除效果要好于高岭土模拟水样。The conditions for extracting the active ingredients of Moringa seeds and the turbidity removal effect of the extract on simulated water samples and actual water samples were studied.The results showed that,when Na Cl was used as theextract,the turbidity removal effect was the best,and the optimal concentration of Na Cl was 0.25 mol/L.With the increase of pH,the optimal dosage of extract increased and the optimal p H was 7~8.The extract of moringa had a good turbidity removal effect for medium and high-turbidity water,and had a poor removal effect for low-turbidity water.The removal effect of actual water was better than the kaolin simulated water.
