引言钡作为一种有毒元素,能够引起对肠胃、心脏、骨骼肌刺激。在我们生活饮用水的检验项目中,钡已经作为检测项目之一,其最大含量不能超过0.7mg/L。在钡的检测中,一般采用火焰原子吸收分光光度法进行测定,因此,本文运用火焰原子吸收分光光度法对水中的可溶性钡和总钡进行测定,结果显示该方法准确性高,操作简便,具有推广意义。随着社会工业的持续发展,各类污染源也逐渐增加。石油、颜料、农药、橡胶等等的富含大量钡盐的化学工业产品在我们日
Introduction Barium, as a toxic element, can cause irritation to the stomach, heart and skeletal muscles. Barium has been used as one of the testing items in our drinking water testing program. Its maximum content should not exceed 0.7mg / L. In the detection of barium, flame atomic absorption spectrophotometry is generally used for the determination. Therefore, the determination of soluble barium and total barium in water by flame atomic absorption spectrophotometry has shown that the method is accurate, easy to operate and has the advantages of Promote the meaning. With the continuous development of social industry, all kinds of pollution sources have also gradually increased. Chemical industry products rich in barium salt, such as petroleum, pigment, pesticide, rubber and so on,
