摘要
研究了用硫酸亚铁 -重铬酸钾滴定分析法测定氯金酸中的金及其测定条件。与质量分析法比较 ,该方法具有操作简单、分析速度快、准确度高的特点 ,相对标准偏差为 0 .16 % 。
The determination of gold in chloroauric acid by titration analysis with ferrous sulphate potassium bichromate and the conditions of chemical reaction are studied.Compared with the gravimetric analysis, the method is simple, rapid and accurate.The relative standard deviation is 0.16%, which is suitable for the determination of gold with high concentration.
