铊是一种有毒稀散元素,它在自然环境中含量甚微。通常用于测定的方法有荧光法,分光光度法、中子活化法、原子吸收光谱法、悬汞电极阳极溶出伏安法等。但这些方法如中子活化法不易推广,其它各方法用于环境污染监测灵敏度还不够。玻璃碳汞膜电极阳极溶出法可以达到较高灵敏度,这种方法已经用来测定海水、尿中的铊,但测定土壤中的铊尚未见有文献资料报道。我们试验了在不同介质中铊的阳
Thallium is a toxic and dilute element, it is very low in the natural environment. Commonly used in the determination of the method of fluorescence, spectrophotometry, neutron activation, atomic absorption spectrometry, hanging mercury electrode anodic stripping voltammetry. However, these methods such as neutron activation method is not easy to promote, the other methods for environmental monitoring sensitivity is not enough. Anodic stripping method of glassy carbon-mercury film electrode can achieve higher sensitivity. This method has been used to determine thallium in seawater and urine. However, there is no literature report on the determination of thallium in soil. We tested for thallium in different media
