工业上广泛应用的二异氰酸酯类化学毒物中，对人体健康危害最大的是２，４二异氰酸甲苯酯（ＴＤＩ）。国内长期以来一直沿用分光光度法对其进行监测，其灵敏度远远达不到现行卫生标准（０．１４ｍｇ／ｍ３）对测定空气中低浓度水平ＴＤＩ的要求。我们研究了高效液相色谱测定
Among the diisocyanate chemical poisons widely used in industry, 2,4-diisocyanatotoluene (TDI) is the most harmful to human health. China has long been using spectrophotometry to monitor its sensitivity is far below the current health standards (0.14mg / m3) for the determination of air in the low concentration level TDI requirements. We studied high performance liquid chromatography
