摘要
Abstract
In this paper introduces the research status of direct current electrochemical platinum dissolution technology.The effects of current density,hydrochloric acid concentration and hydrochloric acid temperature on the dissolution efficiency of platinum are investigated.The results show that under the condition of 100℃,hydrochloric acid concentration 10.01mol/L and current size 1A,the dissolution rate of pure anode platinum electrode is the fastest,reaching 0.138gcm-2h-1.The use of direct current electrochemical platinum not only abandonds the use of nitric acid,but also reduces the amount of hydrochloric acid,and eliminates the emission of nitrogen oxides,which has better economic and social benefits.关键词
