The simultaneous determination of iron, copper, zinc content in balsam pear was conducted adopting the method of flame atomic absorption and spectrophotometer method. Sample pretreatment method screens and acidity condition tests were performed. The results showed that dry ashing is simpler than the wet method, with no loss in the measured elements; the acid medium and the amount to be added have a slight influence on the measured elements; and this test method is of high precision, simple in operation, and strong practicability, which provides a basis for further development of the scientific determination method.
