【Abstract】 The phosphorous content in the high,medium and low carbon manganese iron alloy is measured up by ICP-AES method in which trace amount of nitric acid and hydrochloric acid is dissolved under the heating condition.The work conditions for the instruments are determined and a set of analytical method established through a series experiments.The accuracy of this process RSD is less than 5?% and satisfactory results are achieved by comparative analysis.This method is believed to be fast and accurate and can basically meet needs in actual production condition.更多还原
