摘要
硫化橡胶中由于黏合剂的加入带入钴盐,传统的钴测定方法有比色法、滴定法等。探索使用国产原子吸收分光光度计TAS-990进行测定,详细介绍了测试操作过程,通过试验验证结果可见,国产TAS-990原子吸收分光光度计用于测定硫化橡胶中钴含量,操作方便简捷,测试准确度、灵敏度能够达到并满足化学分析试验方法要求。
Since the adding of binder, vulcanized rubber always has cobalt. The conventional determination method of cobalt is the colorimetric method and the titration method. In this paper, application of domestic atomic absorption spectrophotometer TAS-990 in measuring cobalt in vulcanized rubber was explored; detail process of testing operation was described. The test results show that domestic TAS-990 atomic absorption spectrophotometer can be used for measuring cobalt content of vulcanized rubber; it is simple and easy to operate. Its test accuracy and sensitivity can be achieved to meet the requirements of chemical analysis test methods.
