黑箱理论用于甲醇废水的色谱分析

Application of Black-box Theory to GC Analysis of Waste Containing Methanol

利用黑箱理论对色谱条件进行了优化。对于甲醇废水，由ＧＣ／ＭＳ定性，用ＧＤＸ－２０３＋５％聚乙二醇－２０Ｍ作固定相，ＦＩＤ检测。建立了分析甲醇废水中痕量级Ｃ１－Ｃ５醇的气相色谱分析方法。检测下限：Ｃ１—Ｃ３醇为１μｇ／ｍｌ，Ｃ４醇为３μｇ／ｍｌ，Ｃ５醇为４μｇ／ｍｌ。

The GC optimal conditions were estimated basedon black-box theory. GC/MS was used for qualitative analysis of methanol wastewater. On theGPX-203 (60-80 mesh) coated with 5% PEG 20 M, C1-C5 alcohols in methanol Wastewaterwere quantitatively analyzed by means of FID.The detection limits were 1μ/ml for C1-C3 aloerhcfs, 3μg/ml for C4 alcohols, and 4μg/ml for C5alcohols.
