Abstract |
Macrocyclic ligand resins were synthesized by mixing 1-aza-18-crown-6 into styrene (2th petroleum in 4th class of hazardous materials) divinylbenzene (DVB) copolymer with crosslink of 1%, 2%, 5% and 20% by substitution reaction. The synthesis of these resins was confirmed by content of chlorine, element analysis, electron micrograph, and IR-Spectrum. The effects of pH, time, crosslink of resins and dielectric constant of solvent on adsorption of metal ions by resin adsorbent were investigated. Metal ions showed a great adsorption in over pH 4 and adsorption equilibrium of metal ions were about two hours. In addition, adsorptive selectivity of resin in ethanol solvent was uranium (VI) > copper (II) > gadolinium (III) ion and adsorption of uranium ion was 1%, 2%, 5% and 20% according to the order of crosslink and was inversely in proportional to the order of dielectric constant of solvents. |
