Abstract
Nitrate is one of pollutants which is found in water and dangerous for human health. Spectrophotometer UV Vis method using cadmium reduction is a simple method and cheap but it has a difficult technique and can be used for nitrate analysis. The method was validate according with analytical parameters. The result of this study were linear range 0.069- 5 mg.L- 1, limit detection and quantitation were 0.025 mg.L-1 and 0.069 mg.L-1, respectively. repeatibility of the method 2.19 % rsd and accuracy with 102.7 % recovery. All of parameters have a good performance and can be used for nitrate analysis for water sample.
