| 摘 要： | 提出了改性炭黑－氯化碳黑的分析方法，即样品在管式炉中通氧灰化，使结合在炭黑有机官能团上的氯转化为可测定的无机氯，用吸收液吸收后，汞量法测定氯含量，方法简便快速，准确度高，回收率在９６．８％－１０１．７％，精密度好，相对标准偏差为１．１７％，不需用特殊仪器，适合工业生产中的监控分析。

| Abstract: | A mercurimetric method for the determination of chlorine in chlorinated carbon black is reported in this paper. The sample is burned and ashed in a tubular furnace under an oxygen atmosphere, so as to transform the chlorine combined to the organic functional group of the carbon black to inorganic chloride and to be determined by mercurimetric titration. The method is proved to be simple and rapid and has high accuracy and precision. The recovery is in the range 96. 8%~101. 7% and the relative standard deviation is 1.17%. |
