1.本文报告用隣氨基苯砷酸作檢定与测定少量金(Ⅲ)的結果。限界濃度为1:8,000,000,灵敏度为0.6[D]5。2.找出用比色法測定少量金的合适条件,設計了測定步驟。直至濃度为370微克金(Ⅲ)/50毫升尚符合Beer定律。3.文中討論一些离子对測定的影响,其中有不少陽离子的影响是相当显著的。Pt+4亦有与Au+3同样反应,加热后反应且更灵敏。

A stdy has been made of the possible use of o-amino- benzene arsonic acid as a reagent for qualitative detection of small amounts of gold.In one percent solution,the reagent gives a red coloration or precipitate with the latter.Limit of identificanon is 0.6 [D]5 or concentration limit,1:8,000,000,when tests are performed in test tube.host ions that interfere can be removed by pH adjustment,or with complez-forming reagonts.
