New Convenient Dissolution of Iron-Rhodium Alloys Using Hydrochloric Acid Containing a Small Amount of Nitric Acid without Heating for an ICP-AES Analysis

A new convenient dissolution method for Fe-Rh alloys has been developed. Aqua regia has been used for the dissolution of rhodium alloy samples. However, it is difficult to dissolve high-concentration rhodium (more than 50 mass%) in aqua regia, because a rhodium-passivity on the alloys surface occurs...
