The method of determining the content of copper ion in salt product with spectrophotometry by experiments has been proposed. The technical contents of study, including the existance of copper ion, the method of determining copper ion, the experimental condition and selection of determiniing copper ion in salt product by spectrophotometry, the feasibility of method, the application and comparison of the results for determination were introduced. The results showed that the method is simple, speedy,widespread and high accuracy and precison. Meanwhile it can be used to determine trace copper ion in salt product and food.
