천술료용Na2O5용융，우4~5NHCL용액중용철분환원제잡질As、Cu등，이Al환원고개Sn전량법완성측정。해방법유조우제고금속평형，여이시점계산가제고금속평은1%석사、동사급경두중측Sn조작규정。
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.
