关于锡渣、铜渣及硬头中测锡方法的改进方法

摘要

Paper describes the use of Na2O5 melt in 4~5NHCL solution by reduction with iron powder impurities As, Cu, determination to complete the reduction with Al high Sn iodometric method. This method is helpful to improve the balance of metal, such as pilot calculation procedures to improve Sn measuring metal smooth 1%tin slag, copper slag and hard in the head.%阐述了用Na2O5熔融，于4~5NHCL溶液中用铁粉还原除杂质As、Cu等，以Al还原高价Sn碘量法完成测定。该方法有助于提高金属平衡，如以试点计算可提高金属平稳1%锡渣、铜渣及硬头中测Sn操作规程。
