摘　　要：提出了一种快速测定活性炭对四氯化碳的吸附值新方法。详细介绍了测定的系统装置、控制条件和操作步骤；阐明了通过穿透曲线测定活性炭对四氯化碳吸附值的原理；分析了规定的四氯化碳吸附值的物理意义。该方法测定快速、操作简易，数据精度符合要求。A new method for determining carbon tetrachloride adsorption activity of active carbon with thefrontal chromatograpby has been developed. Equipment,experimental conditions and operational proce-dures are reported in detail.The significance of carbon tetrachloride adsorption activity which is calculatedonly by means of measuring the penetrating curve is interpreted. The proposed technique is convenient and rapid with the same precision as that attained by ASTM method.
