A method was developed for the quantitative determination of total vanadium concentration in mussels via electrothermal atomic absorption spectrometry (ETAAS). After the microwave digestion of the samples, a program using temperatures of 1600 degrees C and 2600 degrees C for ashing and atomization respectively, without any matrix modifiers, allowed us to obtain results that were satisfactory since they agreed closely with certified reference material values. The detection limit was 0.03 mg kg(-1) (dry weight), indicating that the method is suitable for the analysis of mussel samples. This determination was compared with matrix modifiers that have been reported previously. The method was applied to various cultivated and wild mussels from the Galician coast, yielding levels below 1 mg kg(-1) (wet weight).
开发了一种通过电热原子吸收光谱法(ETAAS)定量测定贻贝中总钒浓度的方法。在对样品进行微波消解后,采用分别在1600℃和2600℃下进行灰化和原子化的程序,无需任何基体改进剂,就能获得令人满意的结果,因为这些结果与认证参考物质的值非常接近。检测限为0.03 mg kg⁻¹(干重),表明该方法适用于贻贝样品的分析。将该测定方法与先前报道的基体改进剂进行了比较。该方法应用于加利西亚海岸的各种养殖和野生贻贝,其含量低于1 mg kg⁻¹(湿重)。
