摘要
用萃取剂N_(235)(多种叔胺混合物)浸渍大孔苯乙烯-二乙烯基苯吸附树脂(SDAR)制备了溶剂浸渍树脂(SIR)。研究了浸渍和SDAR合成条件与SDAR对N_(235)的吸附率的关系及N_(235)在SDAR基体上的分布情况,测试了SIR的孔结构及热稳定性。红外光谱表明,N_(235)在SDAR基体上属于物理吸附。
Solvent impregnating resins (SIR) have been prepared by impregnating macroporous styrene-divinylbenzene copolymer adsorption resins (SDAR) in the solution of extracting agent N235. The effects of some synthetic conditions on the adsorption capacities of the SDAR for N235,and the distribution of N235 in the SIR .,and the pore structure of SIR were studied. The relations between impreganting conditions and adsorption capacities were also investigated. The thermal stability of SIR was determinated by TG and the adsorption type of N235 in SDAR was showed by IR.
