Penentuan Kadar Nitrogen Dioksida (No2) dalam Udara Ambien dengan Metode Griess Saltzman Secara Spektrofotometri

Abstract

The determination of the amount of Nitrogen Dioxide at the ambient air by Griess Saltzman method using UV-Visible spectrophotometer with a wavelength of 550 nm. The concentration of nitrogen dioxide obtained from sample i, ii, iii, and iv, are -0.0034 mg/L, -0.0035 mg/L, -0.0036 mg/L, and -0.0034 mg/L. Based on the rule of Ministry of Health of the Republic of the Indonesia No.1405/MENKES/SK/XI/2002 at 19th November 2002, that the concentration had been mentional above are still lower compare to the prohibited concentration, where the level of 5.60 mg/m3 equals to 3,0 ppm
