Objective:To determine the content of cerium oxide and the leaching amount of cerium element in glass ampoules and investigate the relationship between the two.Methods:Inductively coupled plasma atomic emission spectroscopy was used to determine the cerium oxide content and cerium elemental leaching amount in 83 batches of glass ampoules.Results:The maximum content of cerium oxide in 83 batches of glass ampoules was 0.370%,and the maximum leaching amount of cerium element was 0.0397mg/L,showing a certain positive correlation between the two.Conclusion:In the production process of glass ampoules,in addition to controlling the cerium oxide content,other factors need to be comprehensively considered to control the leaching amount of cerium element.
