该研究采用内置纯水电解制氢技术,以无人值守模式,建立了新型液相色谱-原子荧光光谱法(LC-AFS)测定鱼类水产品中汞形态的分析方法。结果表明,3种汞形态在0~100 μg/L范围内线性良好,相关系数(
r
)均大于0.999。无机汞、甲基汞、乙基汞的检出限分别为0.005、0.004、0.004 mg/kg,甲基汞测定灵敏度较传统的LC-AFS大幅提高;不同浓度水平的加标回收率为81.0%~107%,相对标准偏差(RSD)均小于5%;有证标准物质金枪鱼(ERM-CE464)和鱼肉标准参考物质(GBW10029)中汞形态的测定结果均在证书标准值范围内。采用该方法在某些深海鱼中发现较高的甲基汞,提醒关注肉食性鱼类中甲基汞引发的食品安全问题。该方法可大幅节约盐酸、硼氢化钾和过硫酸钾的用量,减少废液生成量;采用独特的同心结构半屏蔽式矩管,在有效避免荧光猝灭的同时,还可大幅降低氩气用量。方法灵敏度高、准确性好,适用于鱼类水产样品中汞形态的分析测定,是一种低成本、绿色环保的汞形态分析方法。
To align with the development trend of green analytical chemistry,this study adopted built-in pure-water electrolysis hydrogen generation technology,and utilizing an unattended mode established a novel analytical method for mercury speciation determination using liquid chromatography-atomic fluorescence spectrometry(LC-AFS). The experimental results revealed good linearity of the mercury species concentrations in the range of 0-100 μg/L,with correlation coefficients(
r
) exceeding 0.999. The inorganic mercury,methylmercury,and ethylmercury detection limits were 0.005,0.004,and 0.004 mg/kg,respectively. The methylmercury determination sensitivity was significantly improved compared with that of traditional LC-AFS. The recoveries at different concentration levels ranged from 81.0% to 107%,and the relative standard deviations were less than 5%. The mercury speciation determination results for the certified reference materials,namely,tuna(ERM-CE464) and fish muscle(GBW10029),were both within the range of the certified standard values. Certain deep-sea fish have been shown to contain high levels of methylmercury,which emphasizes the food safety concerns associated
with methylmercury in carnivorous fish. Compared with the currently mainstream traditional LC-AFS method for mercury speciation determination,the proposed method significantly reduced the usage of hydrochloric acid,potassium borohydride,and potassium persulfate,and decreased the waste-liquid generation. Additionally,this technique employed a unique concentric-structure semi-shielded rectangular tube,which effectively prevented fluorescence quenching while substantially reducing the argon-gas consumption. Overall,the proposed method is highly sensitive and accurate and suitable for the analysis and determination of mercury speciation in fish aquatic samples. Moreover,this method constitutes a low-cost and environmentally-friendly mercury speciation analysis technique.
