Rapid Determination of Petroleum Hydrocarbon Contaminants in Aquatic Products by Fluorescence Spectrophotometry
摘要
Abstract
Determination of fluorescence spectrophotometry is established analysis methods of petroleum hydro-carbon residues in aquatic products.Samples and excessive alkali liquor under the environment of anhydrous ethanol,40 ℃ water bath avoid light vibration wave five hours,fully by the methylene chloride extraction after saponification,negative pressure dry,aromatic petroleum ether dissolved,fluorescence spectrophotometry.Re-sults show that the oil standard fluid in 0.0 ~ 10.0 ng /ml linear relationship is good,the correlation coeffi-cient of 0.9996,the detection limit of 0.85 mg /kg,added mass concentration is 5.0 ~20.0 mg /kg,recov-ery is between 91 .5% ~97.9%.Compare to GB17378.6-2007,the method saves time,saponification,ac-curacy of test results is good,high precision,suitable for detection of petroleum hydrocarbon content in aquat-ic products.关键词
