目的:建立海产品中6种工业染料快速检测方法。方法:样品采用乙腈直接匀浆提取、浓缩,C18色谱柱(250×4.6 mm,5μm)洗脱分离,紫外检测器检测,外标法定量。结果:6种工业染料在0 mg/L～5.0 mg/L范围内线性关系良好,相关系数r>0.999,检测限均达到0.04 mg/kg。回收率范围为78%～99%,相对标准偏差均小于7%。结论:该方法快速、简便、实用,适合基层单位日常工作检测使用。
Objective: To establish a rapid detection method for 6 kinds of industrial dyes in seafood. Methods: The samples were extracted with acetonitrile, concentrated and separated by C18 column (250 × 4.6 mm, 5 μm). The samples were detected by ultraviolet detector and quantified by external standard method. Results: The linear relationships of 6 industrial dyes in the range of 0 mg / L ~ 5.0 mg / L were good with the correlation coefficient r> 0.999 and the detection limit of 0.04 mg / kg. The recoveries ranged from 78% to 99% with relative standard deviations less than 7%. Conclusion: The method is rapid, simple and practical, suitable for routine testing of grassroots units.
