| Abstract: |
| Content of rare earth elements in the electroplating process can be determined rapidly and correctly with chlorophosphonazo Ⅲ by spectrophotometric analysis. The relationship between the absorbency and the dosages of developer, and of the masking agent has been investigated. The labeled recovery of rare earth elements is between 97.7%~101.3%, it suggests that this method is correct and reliable. |
