摘要
本研究包括:(1)流动载体TNOA和N_(1923)的比较.(2)搅拌速度对提取钯的影响.(3)表面活性剂浓度、流动载体浓度、油内比和水乳比四因素正交试验.在本实验条件下对于含钯100ppm左右的料液和废水,其提取率可达97％以上,内相钯的富集浓度可达1000～3000ppm.用乳状液膜提取钯是一项很有希望的技术.
Present work includes; (1) comparison experiments of mobile carriers:TNOA and N_(1923). (2)effect of stirring speed on extraction of palladium. (3) orthogonal test of four factors:surfactant concentration, mobile carrier concentration.oil—inner phase ratio and Span 80 concentration. Extraction of palladium (Ⅱ) from a dilute solution by an emulsion liquid membrane is a highly promising technique.
