摘要
指出了在硫氰酸汞比色法测定空气中氯化氢的过程中,实验室空白信号值较高且变异性较大,通过实验检验了空白的来源,得出了试剂中微量杂质氯离子干扰的主要来源。
In the process of determination of hydrogen chloride in air by thiocyanate cyanide colorimetric method, the blank value of the laboratory is high and with high variability. In this paper, the blank source is tested by experiments. The result showed that trace impurity chloride ion is the main interference.
