摘要
本文报导用气相色谱法测定水中苯酚、邻甲酚、间甲酚、对甲酚、2.4-二甲酚、2.5-二甲酚和3.5-二甲酚。采用的分析条件是:2m×3mm内径的不锈钢柱,12％阿皮松L,0.5％聚乙二醇20M和1％抗坏血酸涂于70-80目的酸洗、硅烷化铬姆沙伯载体上,氮气作为载气,流速55ml/min,氢火焰离子化检测器,柱温137℃,进样量0.2μl.此法简单、快速、准确、重复性好.
This paper reports the gas chromatographic method for the determination of phenol, O-cresol, m-cresol, P-cresol, 2.4-xylenol, 2.5-xylenol and 3.5-xylenol in water. The analytic conditions employed are follows.. Stainlessstell Column 2m×3mm I. D., 12% Apiezon L, 0.5% Carbowax 20M, and 1% ascorbic acid on 70-80 mesh Chromosorb W AW DMCS, Nitrogen as carrying gas, flowing rate 55ml/min, Hydrogen flame ionization detector, Column temperature 137℃ and Sample 0.2μl. This method is simple, rapid, accurate and repeatable.
