硒(Se)是一种具有多种有益功能,在人类生命活动过程中必不可少的微量元素。硒在人体中的含量为14 mg~21 mg,主要分布在肝、胰、肾脏中,硒的量不足或过量都对人的健康有极大的影响。自然环境中的硒主要通过食物链影响人类健康,而饮水又是食物链中的主要环节,为此,快速、准确的测定水样品中的硒对于水中硒含量调差以及水中硒对当地环境影响评价研究至关重要[1]。水中硒主要以无机的Se6+、Se4+、Se2-及某些硒的形式存在,常用的检测方法有比色法[2]、气相色谱
Selenium (Se) is a trace element that has many beneficial functions and is essential in human life and activity. Selenium in the human body content of 14 mg ~ 21 mg, mainly in the liver, pancreas, kidney, the amount of selenium deficiency or excessive have a great impact on human health. In the natural environment, selenium affects human health mainly through the food chain, and drinking water is the main link in the food chain. Therefore, the rapid and accurate determination of selenium in water samples for the adjustment of the selenium content in water and the selenium on the local environmental impact assessment It is crucial [1]. Selenium in water is mainly in the form of inorganic Se6 +, Se4 +, Se2- and some selenium. The common detection methods are colorimetry [2], gas chromatography
