| The on-line element analysis in hydrometallurgical process is introduced in this paper.The principles,methods and on-line calibration of OTI95 is introduced based on the on-line analysis and measurement on Co content in solution purification in zinc hydrometallurgy with OTI95 titrator at Zhuzhou Smelter.This OTI95 titrator has the advantages of less maintenance,reasonable sampling structure,higher adaptability in the site environment,reliable operation, etc.But the analysis cycle should be further shortened. |
