摘要
研究了常压氢还原法分离铱溶液中微量铑的方法,并考察了温度、氢气流量、反应时间、铑的初始浓度和溶液中的盐酸浓度等因素对选择性还原铑的影响。研究结果表明在一定条件下,氢还原可使实际铱溶液中铑降到0.0007g/L,而铱基本上不会被还原。
The method of selective reduction of rhodium by normal pressure hydrogen to seperate trace rhodium from iridium solution was studied. The effects of temperature, hydrogen flow rate, reaction time, initial rhodium concentration and concentration of HCI were investigated. Under a certain condition, the rhodium concentration in the residual solution is 0.0007g/L, the change of concentration of iridium is little in the experimental condition.
