| 内容記述 | The mechanism of copper adsorption by polyvinyl polyacrylate （PVPA） was examined by using ESR and magnetic measurements. The copper adsorption by PVPA was obeyed Langmuir adsorption isotherm with the maximum adsorption amounts of 4.17 mmol/g adsorbent, being larger than those of uranium adsorption. Though copper in the solution was completely adsorbed by the resin above pH 4, the ESR intensity was remained low level and only increased above pH 8. The ESR spectrum of Cu（II） ion in PVPA are axial type with tetragonally distorted octahedral symmetry, having parameters of g// = 2.361, g⊥= 2.057, |A//| = 14.0 mcm−1 （pH 5）, and g// = 2.329, g⊥= 2.058, |A//| = 16.2 mcm−1 , |A⊥| = 2.7 mcm−1 （pH 9）. The absorption peaks originated from Cu（II）-Cu（II） dimer was also observed （pH 5）. The paramagnetic susceptibility of PVPA adsorbed Cu（II） ion at pH 5 explained by the dimer model with |J| = 220 K. These results suggested that most of copper was adsorbed and formed dimer in PVPA, being similar as that in Cu（II）-acetate monohydrate. |
