以次氧化锌酸性浸出液为原料,采用两段溶剂萃取的方法实现铟与其他金属离子的有效分离,并循环利用工艺过程中使用的盐酸,减少氯离子的排放。研究采用P204从浸出液中萃取、盐酸反萃铟的行为,以及采用TBP/P350混合萃取剂从P204载铟有机相盐酸反萃液中选择性萃取铟、水反萃等过程中铟的行为,考察萃取剂浓度、混合时间、酸浓度和相比等因素对铟萃取率和反萃率的影响。结果表明:采用10%P204(体积分数)在相比(A/O)为2/1的条件下,经过2级逆流萃取,浸出液中99%铟被萃取,得到的P204载铟有机相采用6 mol/L盐酸反萃,铟反萃率达100%。得到的含铟盐酸反萃液再采用TBP/P350选择性萃取铟,在相比为3/2条件下,经过2级逆流萃取,铟萃取率为99%,得到的载铟有机相采用纯净水进行3级逆流反萃,铟被反萃完全。与传统工艺相比,氯离子排放量减少86%。基于上述实验结果,提出从次氧化锌酸性浸出液中萃取分离铟的工艺流程,在实现铟高效回收的同时,降低氯离子的排放,达到资源高效利用和减少污染物排放的目的。

Spike-frequency adaptation is a prominent aspect of neuronal dynamics in neural information processing. The external electric field has an effect on the dynamic behavior of the neural system, affecting the generation and conduction of neural information. Based on the Ermentrout model, a modified Ermentrout model under the external electric field is established. From the membrane potential curve and spike frequency curve both changing with time and the onset spike frequency curve changing with the input signal, the changes of the adaptability and the requirements met by the external electric field for the adaptive model are given. The research results suggest a functional role for the external electric field in the excitability of biological nervous system and pathogenesis of several neurological diseases.
