P212 非熱平衡プラズマによる機能性リグノフェノールの貴金属回収に関する研究II : 4級アミン型架橋リグノフェノール(ポスター発表)

抄録

Quaternary amine type derivative of lignophenol (TMA-CLP) has been prepared by electron beam irradiation followed by chemical treatment with trimethylamine. The adsorbent was tested for its adsorption behavior for a number of metal ions and found to exhibit selectivity for Au(III), Pd(II), and Pt(IV) in 0.5 to 5.0 M hydrochloric acid medium. From the adsorption isotherm study, the maximum loading capacity of TMA-CLP for Au(III), Pd(II), and Pt(IV) was evaluated as 4.3, 0.74, and 1.3 mol/kg of the dry adsorbent, respectively.
