Characters of Kinetic and Equilibrium of Adsorption of Eu(III) by an Cation Exchange Resin
The sorption and desorption behaviors of Eu(III) from aqueous solutions with cation exchange resins containing carboxyl groups (D155 resin) were studied in terms of varied Eu(III) concentration, adsorbent dosage, pH, contact time and temperature. Batch shaking sorption experiments were carried out to evaluate the performance of D155 resin in the removal of Eu(III) from aqu...
متن کاملPreparation of novel polyamine-type chelating resin with hyperbranched structures and its adsorption performance
This paper explored the method of combining atom transfer radical polymerization (ATRP) technology and hyperbranched polymer principle to prepare the high capacity chelating resin. First, surface-initiated atom transfer radical polymerization (SI-ATRP) method was used to graft glycidyl methacrylate (GMA) on chloromethylated cross-linked styrene-divinylbenzene resin, and then the novel polyamine...
متن کاملThe preparation of diphosphopyridine nucleotide with ion exchange resin.
The older methods for the preparation of diphosphopyridine nucleotide (DPN) were reviewed in 1942 by Schlenk (1). In 1947 Sumner et al. (2) outlined the need for a greatly simplified method for the preparation of this coenzyme. These authors described a procedure which did away with heavy metal fractionation. Recently, Clark et al. (3) made several modifications in the above method. The LePage ...

متن کاملStudying effects of ion exchange resin structure and functional groups on Re(VII) adsorption onto Purolite A170 and Dowex 21K
The effects of the functional groups and structures of two different resins, weak base/macroporous and strong base/gel type, Purolite A170 and Dowex 21K on the adsorption properties of Re(VII) ions were investigated experimentally and described by the isotherm, kinetic, and thermodynamic modeling. In this regard, four widely used adsorption isotherm models including Langmuir, Freundlich, Temkin...
