摘要 研究了用二-(2-乙基己基)膦酸(P204)-熔融石蜡在60℃对金属铜的固液萃取行为,探讨了酸度、萃取剂浓度、Cu2+浓度、稀释剂用量及搅拌时间等因素对金属铜萃取率的影响.用斜率法确定了萃取机理,测定并计算出了表观萃取平衡常数Kex和相关热力学参数. The solid-liquid extraction behavior of copper with di(2-ethylhexyl) phosphoric acid(P204) into molten paraffin wax has been studied in the paper. The effects of time to achieve equilibrium, diluent dosage, copper (II) concentration, P204 concentrotion, pH on the extraction are discussed. The stoichiometry of the extracted species of copper(II) is determined on the basis of slope analysis method. Extraction equilibrium constant and thermodynamic data are also determined and discussed.
