Study on the Determination of Total Nitrogen in Barkol Lake by Ultraviolet Spectrophotometry
Total nitrogen is a key index to evaluate whether the water quality is polluted or not.The total nitrogen content in the water sample of Barkol Lake was analyzed by ultraviolet spectrophotometry.The total nitrogen concentration value of Barkol Lake was obtained by the preparation of standard curve and the determination of samples,and the data analysis and result interpretation were carried out.A reliable method for the determination of total nitrogen was constructed to provide a scientific basis for the water quality evaluation of Barkol Lake.Finally,the method of removing the influence of high salt content on the determination of total nitrogen was analyzed.It can provide important data for water quality evaluation of Barkol Lake,and also provide experience and reference for water quality analysis in other related fields.
