Abstract:
The article establishes a method for the continuous determination of iron, lead, and zinc in crude copper by inductively coupled plasma emission spectroscopy after dissolving the sample with nitric acid. Through experiments, the instrument conditions and the interference of coexisting ions were investigated. Under the selected experimental conditions, the linear range of iron, lead, zinc, arsenic, bismuth, nickel, and antimony is 010mg/L, and the working curve has a good linear relationship; the recovery rate of actual sample analysis is 93.7%103.2%. The relative standard deviation (RSD) of precision in actual sample analysis is less than 9.2%. This method is simple to operate, efficient, and can meet the analysis requirements of impurity elements in crude copper with both accuracy and precision.
