Improvement Of Water, Vanadium, Chromium, Beryllium, Arsenic, Mercury Analysis

Water is important to the survival of animal and plant. With the increasing improvement of standard of living of people, the demand for living environment is more and more stringent. But with the development of industry and agriculture, water quality is increasingly subjected to breakage and harmful substance in water is more and more.There are thousands of corporations which produce various products in the Jinshajiang River located headwaters of the Changjiang River. This will affect water quality of the Jinshajiang River. The measuring method of harmful elements in water is studied in order to control the harmful elements in water and provide safeguard for industry and agriculture production and life of people.The measuring lower limit, optimum wavelength, optimum acidity, incidence power, pressure of atomizer, lifting capacity of solution and assistant quantity of gas flow are studied using ICP—AES spectroscope in this paper. The recovery test indicates the chosen conditions are reasonable. On the basis of this the measuring method of vanadium, chromium and beryllium in water is established.The effects of temperature of arsenic and hydrargyrum in water, carrier gas, height of beam of light, concentration of sodium borohydride on fluorescence intensity are studied using hydride induced-atomic fluorescence photometer. The measuring lower limit is determined. The measuring method of arsenic and hydrargyrum in water is established.The test of measuring water indicates the established measuring method is fast and exact. The test results indicates the content of five harmful elements in water of the Jinshajiang River is too low to lead harmful effects on industry and agriculture production and life of people.
