Analisa Kadar Nitrat dan Nitrit pada Air Minum dengan Metode Spektrofotometri UV-Visible di UPT. Laboratorium Kesehatan Provinsi Sumatera Utara

Abstract

Analysis of Determination of Nitrate and Nitrite Levels of Drinking Water using UV-Visible Spectrophotometry method at UPT.Laboratorium Kesehatan North Sumatra Province. Nitrate and Nitrite Levels have been examined by UV-Visible Spectrophotometry at wavelengths of 220 nm for Nitrate, 543 for Nitrite. In the Nitrate test using 6 samples of drinking water from different sources. The results of the analysis obtained by the nirat content in drinking water still meet the Quality Standard, limit of 50mg / L. In the six test samples Nitrate 0.1366 mg / L; 0.1904 mg/L; 0.4716 mg/L; 0.0178 mg/L; 0.0946 mg/L; 0.0578 mg / L. In testing Nitrite levels using 8 samples of drinking water from different sources. The results of the analysis obtained Nitrite levels in drinking water samples still meet the Quality Standards limit, 3mg / L. In the eight samples of drinking water tests using UV-Vis Spectrophotometry, which is 0.0156 mg / L; 0.0119 mg/L;0.0038 mg/L;0.0020 mg/L;0.0055 mg/L;0.0078 mg/L;0.0108 mg/L; 0.0057 mg/L. Based on the data obtained from the analysis of nirate and nitrit levels in drinking water, it meets the water quality standards set by the minister of healsh of healts of the Repulic af Indonesia No.492/MENKES/PER/IV 2010.
