Dear Riina, I want to analyze antimony in ore (the ore is rich in lead, silver, antimony and arsenic). Can you tell me the dissolution method for antimony? So that I could analyze antimony in ICP-OES. I have tried with aqua-regia and hydrochloric acid but not got good results. 1 Recommendation. Riina Salmimies. 6 years ago.
