| Abstract: | The main problems in determination of gold by the back titration for the excessive FeSO4 with potassium bichromate were discussed and experimented. A simple, accurate and easy to operate method was developed. When the content of gold is from 60% to 99%, the relative standard deviation of <0.2% can be achieved. |
