摘要
采用硝酸预处理-烧碱石棉吸收重量法,结合高频红外碳硫分析仪测定晶质石墨中的固定碳,建立了测定固定碳的分析方法,对样品的称样量、灼烧时间、灼烧温度选择等进行了优化研究,实验证明,该方法流程简单,自动化程度高,分析速度快,结果准确、可靠。适用于一切石墨样品中固定碳的测定。
The nitric acid pretreatment-caustic asbestos absorption gravimetric method was used to determine fixed carbon in aphanitic graphite by high frequency infrared carbon sulfur analyzer. An analytical method for determination of fixed carbon was established. The sample weight, burning time and burning temperature were optimized. The experimental results show that the method is simple, accurate and reliable, and it is suitable for determination of fixed carbon in graphite samples.
