电热空气清新消毒液中樟脑、薄荷醇和冰片的气相色谱法测定

CGC Determination of Camphor, Menthol and Borneol in Electric Heating Air Cleaning Disinfectant

用萘作内标，毛细管气相色谱法测定电热空气清新消毒液中樟脑、薄荷醇和冰片的含量。结果显示，空气清新消毒液含樟脑８．１５％，薄荷醇３．７０％，冰片３．５３％；ＲＳＤ分别为１．３６％，２．１５％，４．５８％（ｎ＝３）。樟脑在０．４９８～２．４９０ｍｇ／ｍｌ，薄荷醇在０．２２７～１．１３５ｍｇ／ｍｌ，冰片在０．２２４～１．１２０ｍｇ／ｍｌ浓度范围内线性关系好，ｒ值均为０．９９９９。樟脑、薄荷醇和冰片的平均回收率分别为９８．６％，９８．９％，９６．５％；ＲＳＤ分别为１．３２％，２．６０％，３．４３％（ｎ＝３）。方法精密度高，重复性好，操作简便。

The contents of camphor, menthol and borneol in Electric Heating Air Cleaning Disinfectant (EHACD) were simultaneous determined by CGC with naphthalene as an internal standard. The result indicated that the contents of camphor, menthol and borneol were 8.15%, 3.70% and 3.53%, respectively. RSD(n=3) were 1.3%, 2.15% and 4.58%, respectively. The standard curve was linear in the range of 0.4982.490mg/ml for camphor, 0.227-1.135mg/ml for menthol and 0.224-1.120mg/ml for borneol. And all rs=0.9999. The average recovery and RSD (n=3) were 98.6% and 1.32% for camphor, 98.9% and 2.60% for menthol, 96.5% and 3.43% for borneol. The method was simple, quick and accurate for simultaneous determination of camphor, menthol and borneol in EHACD.
