[ 1 ] - Adsorption Behavior of Cu(II) in Aqueous Solutions by SQD-85 Resin

The adsorption and desorption properties of SQD-85 resin for Cu(II) had been investigated. A series of experiments were conducted in a batch system to assess the effect of the system variables, i.e. initial pH, contact time and temperature. The results show that the optimal pH for the adsorption was 5.99 in the HAc-NaAc system, and the maximum adsorption capacity was estimated to 324 mg/g a...

[ 2 ] - 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...

[ 3 ] - Adsorption Behavior of MWAR Toward Gd(III) in Aqueous Solution

Adsorption and desorption behavior of Gd(III) ionon macroporous weak acid resin (MWAR) had been investigated.The influence of operational conditions such as contact time, initial concentration of Gd(III) ion, initial pH of solution and temperature on the adsorption of Gd(III) ion had been examined. Experimental data were exploited for kinetic and thermodynamic evaluations ...
