Determination of Fluoride Ions in Copper Concentrate from Beiya Mining Area by Steam Distillation Ion Chromatography and Exploration of its Influencing Factors
The pre-treatment process of using steam distillation ion chromatography to determine fluoride ions in copper concentrate has a significant impact on the final determination results,and the temperature of the pre-treatment process is difficult to grasp.To solve the problem of unstable long-term fluoride detection in the laboratory,exploratory experiments were conducted on four conditions during the pre-treatment process:distillation temperature,different acid media,sulfuric acid concentration,and sulfuric acid addition amount.The optimal conditions during the pre-treatment process were determined,which improved the operability and accuracy of ion chromatography in determining fluoride ions in copper concentrate.
