“…1,2 These resins possessing chelating groups may be used in chromatographic separations of certain metal ions and in the recovery and removal of traces of certain metallic ions from high concentrations of other electrolytes. [1][2][3] Dalal and Kapadia 4,5 reported the ion-exchange properties of phenol-furfural and phenol-acetaldehyde resins. Chelation ion-exchange properties of 2,4-dinitrophenylhydrazone of a 2-hydroxyacetophenone-formaldehyde resin have been reported.…”

“…Ion‐exchange resins show selectivity toward the absorption of various metal ions and possess a high absorption capacity 1, 2. These resins possessing chelating groups may be used in chromatographic separations of certain metal ions and in the recovery and removal of traces of certain metallic ions from high concentrations of other electrolytes 1–3. Dalal and Kapadia4, 5 reported the ion‐exchange properties of phenol–furfural and phenol–acetaldehyde resins.…”

A 2,2 0 -dihydroxybiphenyl-formaldehyde copolymer, synthesized by the condensation of 2,2 0 -dihydroxybiphenyl with CH 2 O in the presence of an acid catalyst, proved to be a selective chelating ion-exchange copolymer for certain metals. The chelating ion-exchange properties of this copolymer were studied for Fe(III), Cu(II), Ni(II), Zn(II), Cd(II), and Pb(II) ions. A batch equilibrium method was employed in the study of the selectivity of metal ion uptake, involving the measurements of the distribution of a given metal ion between the copolymer sample and the solution containing the metal ion. The study was carried out over a wide pH range and in media of various ionic strengths. The copolymer showed a higher selectivity for Fe(III), Cu(II), and Ni(II) ions than for Co(II), Zn(II), Cd(II), and Pb(II) ions.

“…Thorium, uranium(VI), and zirconium showed an adsorption maximum at approximately 8N nitric acid. In recent years anion exchange chromatography has found a wide range of applications in analytical chemistry (11,12, lo) and in radiochemical separations (S, IS,17). The behavior of most elements in hydrochloric acid solutions in equilibrium with the strong base anion exchange resin Dowex 1 has been studied extensively (9).…”

“…Other work of interest in this connection has been reported by Ayres (1). No attempt has been made to survey the literature dealing with the removal of radioactivity by' ion exchange since reviews of the literature of ion exchange appear each January' in Analytical Chemistry (2) and in Industrial and Engineering Chemistry (3). To investigate all the variables in so heterogeneous a solution as a general laboratory' waste was obviously impossible since the waste is never the same from day to day' or even from minute to minute.…”
