摘要
Abstract
Ruthenium chloride(RhCl3)is an important precursor compound for the preparation of rhodium catalysts.To address the challenge of dissolving rhodium powder,an alternating current electrochemical dissolution process was proposed.The effects of factors such as current density,hydrochloric acid concentration,electrolysis time,and electrolysis temperature on the dissolution of rhodium powder were analyzed.This method not only enables rapid dissolution of rhodium powder but also features simple operation.Research indicates that as the current density increases,the dissolution rate of rhodium powder continuously rises,and when the current density exceeds 3 A/cm2,the dissolution rate exhibits a steep upward trend.Over time,the dissolution rate of rhodium powder initially increases and then decreases.As the hydrochloric acid concentration rises,the dissolution rate accelerates,reaching its peak when the concentration reaches 8 mol/L.Further increasing the hydrochloric acid concentration leads to a decline in the dissolution rate.With the rise in electrolysis temperature,the dissolution rate of rhodium powder gradually increases,peaking at 60℃.Beyond this temperature,the dissolution rate begins to decline.关键词
