摘要
用二硫化碳萃取经水稀释过的水性涂料中的苯系物,离心分离后,用毛细管气相色谱测定,用极性柱和非极性柱双柱定性,单柱定量.线性范围为0～120mg/L,相关系数大于0.9996,检出限0.005mg/kg,回收率大于90%.方法快速、准确、灵敏度高、干扰少.
In this paper the determination method of BTEX in water soluble coatings by gas chromatography after the extraction of their water diluted matrix with carbon disulfide is introduced. Use polar and non-polar columns do the qualification and use single column to do the quantification. The liner ranges are 0- 120mg/L （r 〉 0.9996）. The detective limitations are 0.005mg/kg. The recoveries are higher than 90% . This analysis method is rapid and accurate with high flexibility and less interference.
