| 摘 要： | 综述了近几年来测定环境水样中硒的样品前处理方法,主要包括样品消解,加入基体改进剂和分离富集3个方面。消解法中主要使用湿法消解;加入基体改进剂适用于石墨炉原子吸收光谱法的样品预处理,可以提高硒的灰化温度,减少硒的损失以及样品中基体的干扰;固相萃取法是萃取法的主要使用手段。

| Abstract: | The methods of sample pretreatment for analysis of selenium speciation in waters which included sample digestion, addition matrixes modifier, separation and enrichment were reviewed. Wet digestion was mainly used in digestion method. Addition matrixes modifier to pretreatment of sample which can improve ashing temperature and reduce loss of Se and interference of matrixe suited to graphite furnace absorption spectroscopy (GAAS). Stable extraction was mostly used in extraction. |
