摘要
本文建立了直接进样法检测AB-8树脂中二乙烯苯的方法。结果显示浓度与峰面积呈良好的线性关系,r=0.9999;间二乙烯苯的最低检测限为0.08151μg/mL,对二乙烯苯的最低检测浓度为0.0834μg/mL。用该法可达到10-9级(ppb级)的检测限,克服了固体树脂顶空进样法二乙烯苯检测限高的缺点,该法简便、可靠。
A method of detecting divinyl-benzene residues in AB-8 resins by Gas Chromatography was formed.Color saturation with peak area to submit favourable linear correlation,r=0.9999;lowest detectable limit of inter-DVB is 0.0815μg/mL,and anti-DVB is 0.0834μg/mL.Detectability can achieve 10-9 PPb by direct sample introduction to determinate of diethyl-benzene residues in AB-8 resins,and overcome defects of high detectability by headspace sample introduction,this method was simple and rliability.
