-li. Separation of Tb3+, Dy3+, Ho3+, Er3+ with solvent impregnated resins containing Di-(2, 4, 4-trimethylpentyl) phosphinic acid [J]. Journal of the Chinese Rare Earth Society, 2000, 18(3): 265-267... capacity is lower than that of the former (equals 1/2 that of the former)[6-7]. As to the separation coefficient, there is no obvious difference between these two impregnated resins. Since the discovery......
concept of solvent impregnated resins is based on simple immobilization of the most commercially used selective solvents into an inert insoluble support, especially various types of nonfunctional... from undetectable amount (0.02 g/L) to 0.2 g/L. Losses of the solvent from the impregnated resins are negligible in relatively concentrated salt solutions, particularly in the acidic range [12-14......

with ethyl alcohol and HCl(Pre-XAD-16) to prepare the solvent impregnated resins SIRs-INET-3/XAD-16 and SIRs-INET-3/Pre-XAD-16. The molecular weight distribution of the low molecular weight(LMW) polymers washed off by ethyl alcohol during XAD-16 pretreatment was determined by gel permeation chromatography(GPC). The macroporous resins(XAD-16 & Pre-XAD-16), the corresponding solvent impregnated......
