The most effective water to solvent ratio is determined for the analyses of aromatic hydrocarbons in water using hexane. The recoveries of these hydrocarbons formed in the water soluble fraction of crude oils and petroleum products are measured using a microextraction procedure. Recoveries were in the 30-40% range but are consistent for each compound. Fish muscle samples are fortified with the standards and the recoveries measured with a modified extraction procedure using dichloromethane as the primary extracting solvent. This is dispersed in water using acetone and finally extracted with hexane. Recoveries range from 90-113% with a mean value of 98%.
为使用己烷分析水中的芳烃确定了最有效的水与溶剂比例。使用微萃取程序测量原油和石油产品水溶性馏分中形成的这些烃类的回收率。回收率在30%-40%范围内，但每种化合物的回收率是一致的。用标准品对鱼肉样品进行加标，并使用以二氯甲烷作为主要萃取溶剂的改良萃取程序测量回收率。将其用丙酮分散在水中，最后用己烷萃取。回收率范围为90%-113%，平均值为98%。
