本文以苯为稀释剂,考察了2-乙基己基膦酸单2-乙基己基酯(HEll(EHP),P_(507)从硫酸盐溶液中萃取Zn(Ⅱ)的动力学过程。 (一)实验 1.HEH(EHP)按铜盐法提纯,纯度为99.26％.其余主要试剂为A.R.级. 2。自制恒温恒界面反应池,两相分别搅拌,方向相反,以SZGB-11光电转速传感器测定两相搅拌速度,使之基本相等。根据需要可更换反应池内筒调节界面积大小。
In this paper, benzene as a diluent was used to investigate the kinetics of Zn (Ⅱ) extraction from sulphate solution of mono-2-ethylhexyl 2-ethylhexylphosphonate (HEH) and P_ (507) ) Experiment 1.HEH (EHP) was purified by copper salt method with a purity of 99.26%. The other major reagents were AR grade 2. Self-made constant temperature and constant temperature interface reaction tank, the two phases were stirred in the opposite direction to SZGB-11 photoelectric speed sensor Determination of two-phase stirring speed, so that the basic equality.According to the need to replace the reaction tank inner tube to adjust the size of the interface area.
