摘要
研究了辣木籽吸附Cu(Ⅱ)的性能,实验结果如下:随着吸附剂用量增加,Cu(Ⅱ)的去除率从70.84%增至79.66%;当pH由2至6逐渐增加时,去除率由35.7%增至76.9%,去除率的增加都是先快后慢;随着Cu(Ⅱ)浓度5 mg/L增至500 mg/L,去除率从80.4%减少至20.4%;随着Cr6+浓度由10 mg/L增至50 mg/L,Cu2+的去除率从72.1%增加至83.6%。
The performance of moringa seed adsorption Cu（Ⅱ） was studied.Experimental results showed： as adsorbent dosage increased,Cu（Ⅱ） removal rate was increased from 70.84 % to 79.66 %;When pH by 2 to 6 gradually increases,the removal rate increased from 35.7 % from76.9 %,the increase of the removal rate was first after fast slow.With Cu（Ⅱ） concentration 5 mg/L to 500 mg/L,removal rate decreased from 80.4 % to 20.4 %;As Cr6＋ concentration by 10 mg/L to 50 mg/L,Cu2 ＋removal increased from 72.1 % to 83.6 %.
