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。
1. This paper reports the use of o-aminobenzene arsenic acid for the determination and determination of a small amount of gold (Ⅲ) results. Boundary concentration of 1: 8,000,000, the sensitivity of 0.6 [D] ~ 5. 2. Find the appropriate conditions for the determination of a small amount of gold by colorimetric method, the determination of the design steps. Until the concentration of 370 micrograms of gold (Ⅲ) / 50 ml still comply with Beer’s law. 3. The paper discusses some of the impact of ions on the determination of which many of the effects of cations are quite significant. Pt ~ (+4) also has the same reaction with Au ~ (+3), which reacts more sensitively after heating.
