摘要: Abstract In the present work, thiourea-formaldehyde (TF) and urea-formaldehyde (UF) chelating resins have been synthesized they used in adsorptions of Ag(I), Cu(II), Zn(II) metal ions by batch column methods. The effect initial acidity Ag(I) solution adsorption capacities TF UF method separation from Cu(II) base were examined experimentally. found as 58.14 47.39 mg Ag(I)/g 30.7 4.66 mg Ag(I)/g, 0.80 0.121 mg Cu(II)/g, under 0.002 mg Zn(II)/g method, respectively. It was that showed higher affinity towards resin than resin, compared with or ions, could be separated more effectively Cu(II)and ions.
