| 摘 要： | 以恒界面池法研究了氯化物介质中季胺萃锌的动力学。考查了搅拌转速、传质界面积和温度对萃取速率的影响，判定季爱萃锌为界面化学反应的动力学模式。进一步研究了季胺萃取剂浓度和水相Ｚｎ＾２＋浓度对萃取速率的影响，得到了与理论推断相吻合的速率方程。

| Abstract: | The kinetics of zinc extraction in choride medium was studicd using the Lewis cell.Theeffects of stirring speed ,interfacial area of mass transfer and temperature on the extractionrate were examined. Results suggest that the kinetics of zinc extraction using quaternary am-monium is controlled by chemical reaction on the interface, The effects of concentration of qua-ternary ammonium and zinc ions in solution on the extraction rate were also investigated.Arate equation which coincides with theoretical inference was presented as follow:R=12 exp(-2973.609/T)a_i[ZnCl_4][R_4NCl]_(0) |
