Ion-exclusion/cation-exchange chromatography (IEC/CEC) on a weakly acidic cation-exchange resin using on acidic eluent,
Ion-exclusion/cation-exchange chromatography (IEC/CEC) on a weakly acidic cation-exchange resin using on acidic eluent, developed by Tanaka et al. in 1994, has been employed to monitor the quality of environmental water samples such as acid rainwater and river water, to analyze body fluid samples such as saliva, and to evaluate water purification by photocatalytic materials.1–8 One advantage of...
متن کاملAdsorptive Removal of Al, Zn, Fe, Cr and Pb from Hydrogen Peroxide Solution by IR-120 Cation Exchange Resin
Adsorption of cations Al, Zn, Fe, Cr and Pb from aqueous solution of hydrogen peroxide using IR-120 cation-exchange resin was studied. The removal percentage of the cations was examined by varying experimental conditions (such as pH of the hydrogen peroxide solution, temperature, contact time and dosage of adsorbent) i...
متن کاملModeling of Ion-exclusion and Vacancy Ion-exclusion Chromatography on a Strongly Acidic Cation-exchange Resin in the H+ Form
Ion-exclusion chromatography (IEC) can sometimes be used for separation of the weak acids using pure water as mobile phase. Characteristic leading (i.e. frontally tailing) peaks are obtained and retention depends on the concentration of solutes. It was recently shown that this order could be reversed. In vacant ion exclusion chromatography (vIEC) sample flows as mobile phase and pure water is i...
متن کاملApplication of response surface methodology for thorium(IV) removal using Amberlite IR-120 and IRA-400: Ion exchange equilibrium and kinetics
In this work, thorium (IV) removal from aqueous solutions was investigated in batch systems of cationic and anionic resins of Amberlite IR-120 and IRA-400. In this way, the effects of pH, initial Th(IV) concentration and the amount of adsorbent were investigated. A Central Composite Design (CCD) under Response Surface Methodology (RSM) was employed to determine the optimized condition. The resu...
