Abstract: Gold ore contains a certain amount of gold, silver, copper, lead, zinc, arsenic, and antimony, gold needs to be determined after roasting, digestion and enrichment, arsenic and antimony are lost after roasting, while silver, copper, lead, zinc, arsenic and antimony need to be separately determined, which is extremely cumbersome. The experiment utilized the oxidizing properties of hypochlorous acid to oxidize carbonaceous matters and sulfides in nitric acid medium instead of sample roasting, combined with offline internal standards, a method was established for the simultaneous determination of gold, silver, copper, lead, zinc, arsenic, and antimony by ICP-MS. The amount of hypochlorous acid, digestion time, internal standard selection, and interfering elements were optimized, the results showed that 10.0000g of the sample was weighed, 20mL of nitric acid and 5mL of hypochlorous acid were add, the carbonaceous matters and sulfides were basically oxidized after heating plate to dissolve almost dry. According to the experimental method, gold, silver, copper, lead, zinc, arsenic, and antimony were determined in five different types of gold ore samples, the results were consistent with the national standard method, standard deviation (RSD, n=7) were less than 4.71%. This method solves the problem of simultaneous determination of gold, silver, copper, lead, zinc, arsenic, and antimony, which is simple and convenient.
