A review on spectrometer of PB(II) in water

Abstract

Heavy metals have many characteristics such as susceptible to bioaccumulation, ecological amplification effect, and high toxicity and so on. Heavy metal pollution in water not only destroys the ecological environment, but also threat to human health and life seriously. Pb (II) enters the body through the enrichment of animals and plants in water, and damage to the reproductive ability, nervous system and body function of human. Source controlling is the key to the prevention of heavy metal pollution, so we urgently need to apply a plenty of heavy metal fast-detection instrument. we know that the research and development of heavy metal fast-detection instrument is becoming more and more important. However, the existing methods of detection of heavy metals have many problems like its procedure is too complicated, its equipment is expensive and operation process is not suitable for site test. The detection instruments are also numerous and varied, but the classified papers about heavy metal rapid-detecting instrument based on different principle seldom appear. In this paper, the current situation of existing heavy metals rapid-detection instrument based on different principles was reviewed, and the development direction of rapid-detection instrument was pointed out.
