Abstract
|
|
|
|
The effects of pH, time, dielectric constant of solvent and crosslink on adsorption of metal ions by l-aza-18-crown-6-styrene-DVB(divinylbenzene) resin(resin) adsorbent were investigated. The metal ions were showed fast adsorption on the resins in over pH 3. The equilibrium time for adsorption of metallic ions was about two hours and the adsorption selectivity determined in methanol was in increasing order uo₂2+ ＞ Mg2+ ＞ Ho3+ ions. The adsorption was in the order of 1%, 2% and 4% crosslink resin and adsorption of resin decreased in proportion to the order of dielectric constant of solvents.
