铊是由威廉克鲁克斯爵士于1961年发现的一种蓝白色的重质金属,质柔软,其在环境中分布广泛,地壳中的平均含量在0.3~0.5 mg/kg之间。铊曾被作为脱发剂应用于人体,但因导致大量中毒患者而停用,后作为灭鼠剂得到广泛推广。现代工业中,铊在光学系统和光电制造产业中发挥重要作用[1-2]。既往有文献认为由于含量相对较低,具有毒性的铊并非是潜在的污染物[3]。随着制造业的
Thallium, a blue-white heavy metal discovered by Sir William Crooks in 1961, is soft in texture and widely distributed in the environment with an average crustal content of 0.3-0.5 mg / kg. Thallium has been used as a hair loss agent in the human body, but was discontinued due to a large number of poisoning patients and was widely promoted as a rodenticide. In modern industry, thallium plays an important role in the optical system and optoelectronics manufacturing industry [1-2]. Previous literature suggests that thallium, which is toxic, is not a potential pollutant because of its relatively low content [3]. With the manufacturing industry
