Three solvent impregnated resins (SIRs) were first prepared using two types of nonreactive polystyrene-divinylbenzene polymers (HZ818 and HZ830) and one type of reactive weak basic ion exchange resin (D301) as supports and HEHEHP (2-ethylhexyl phosphonic acid mono(2-ethylhexyl) ester) as the extractant. Then the first two prepared SIRs were coated by poly-vinyl alcohol (PVA)-H 3 BO 3 ...
A modified solvent impregnated resin (MSIR) was prepared by impregnation of sec-octylphenoxy acetic acid (CA-12) on styrene–divinylbenzene copolymer support (HZ818) after nitration of the benzene rings present in its structure. The MSIRs were characterized by thermogravimetric and Fourier Transform infrared spectroscopy (FTIR) analysis. The adsorption behavior of indium(III) on MSIRs was examined...
