-
摘要: 研究了多孔有机膨润土颗粒对硝酸根离子的吸附行为.试验了有机覆盖剂的用量、吸附时间、pH值以及硝酸根离子的初始浓度对吸附反应的影响.当覆盖剂用量为45%、硝酸根离子初始浓度为0.05 mg/L、吸附剂用量为10 g/L、pH值为6、吸附时间为60 m in时,去除率达96%.Abstract: Adsorbtion properties of porous organo bentonite on NO_3~- were studied.The effect of time,pH and initial concentration of nitrate ions on adsorption reaction were investigated.The adsorbtion ratio can reach 96% under the following conditions,covering 45%,initial concentration 0.05 mg/L, adsorbent 10 g/L,pH 6,time 60 min.
