摘要
用无水乙醇作吸收液，使异氰酸甲酯转化为取代氨基甲酸酯，用氮磷检测器（ＮＰＤ）检测，可消除其他组分的干扰，方法的检测限可达μｇ／Ｌ水平。该方法比目前使用的分光光度法快速、简便、准确。
Methyl isocyanate was reacted with absolute alcohol(the absorption liqiud)into substituent carbamate which was determined by gas chromatography with NPD.The disturbance of other components could be eliminated.The detection limit reached the level of μg/L.The method in this paper was quic ker,simpler and more accurate than the using way now.
