强酸性阳离子交换剂吸附性能比较

研究强酸性阳离子交换剂对Ca2+、Ag+和Pb2+的吸附性能。用静态法对强酸性阳离子交换剂的吸附性能进行比较。结果表明,本实验室自制的1号和2号Na+型强酸性阳离子交换纤维对Ca2+的静态饱和吸附量分别是204.4mg/g和210.9mg/g;对Ag+的静态饱和吸附量分别是540.4mg/g和557.7mg/g;对Pb2+的静态饱和吸附量分别是1038.1mg/g和1071.2mg/g。结论离子交换纤维与离子交换树脂相比,具有交换速度快、交换量大的优点。

Ca2＋,Ag＋ and Pb2＋ absorption capacity of the strong acidity cationite were stuide, absorption capacity of the strong acidity cationite was compared by static state method.The results showed that the static absorption capacity of No.1 and No.2 sodium ion strong acidity ion exchange fiber for Ca2＋ were 204.4mg/g and 210.9rag/g; the static absorption capacity for Ag＋ were 540.4mg/g and 557.7mg/g; the static absorption capacity for Pb2＋were 1038.1mg/g and 1071.2mg/g.The conclusion showed that the ion exchange fiber had quick exchange rate and high exchange capacity compared with ion exchange resion.
