【摘要】 针对凝胶、泡沫、铈-硝酸、氢氧化钠和硝酸等模拟去污废液,进行了超强吸水树脂类型的筛选和吸液性能的初步研究。结果表明:HH、ND和SJ 3种树脂的吸液比较大、吸液速率较快、耐酸性较好;吸液比、硝酸浓度和实验时树脂包裹的表面积均对吸液性能有影响,吸液速率随吸液比和硝酸浓度的增加而降低。更多还原

【Abstract】 For simulated decontaminating liquid waste generaged from gel,foam,Ce(Ⅳ)/HNO3 and traditional chemical(NaOH or HNO3) decontamination technology,this paper conducted a pilot study on superabsorbant polymer screening and absorption capacity.The results showed that HH,ND and SJ had higher absorption capacity and rate,and could be better resisttant to acid and oxidation.Absorption ratio,HNO3 concentration and package have remarkable effects on absorption capacity.Absorption rate became low with the increase of Kd and HNO3 concentration.更多还原
