Use of Naphthol Blue–black-modified Amberlite Ira-400 Anion-exchange Resin for Separation of Heavy Metal Ions
نویسندگان
چکیده
The potential of naphthol blue–black-modified Amberlite IRA-400 anion-exchange resin for separation of heavy metal pollutants has been explored. The distribution coefficients (Kd) of metal ions in several acidic solvent systems have been studied. The effect of the dissociation constant of the solvent on the distribution coefficient of metal ions has also been investigated. On the basis of Kd values, some analytically important binary separations (Al from Co, Zn from Ni, Zn from Co, Ba from Cd, Ca from Co, Zn from Zr, Al from Zr, Pb from Co, and Zn from La) have been achieved. The practical applicability of the modified material has been demonstrated in the analysis of a synthetic mixture for selective separation of Zr.

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...
متن کاملEquilibrium and kinetics of heavy metal ion exchange
Ion exchange has a great potential to remove heavy metals from industrial wastewaters or heavy metal-containing sludge. In order to design and operate heavy metal removal processes, the equilibrium relationship between ions and resin must be known a prior. A series of ion-exchange equilibrium tests of Cu/H, Zn/H, and Cd/H systems using Amberlite IR-120 were performed. The equilibrium data were ...
