Analisis Kadar Nitrit (NO₂ ) Dari Air Sungai Percut dan Sungai Deli Dengan Metode Spektrofotometri pada Balai Riset Standarisasi Industri Medan

Abstract

The result of analysis nitrite content ( NO2 ) of Percut river water taken in Amplas area and Deli river water taken in Deli Tua area by using spektrofotometri method it has wavelength 543nm observed since a weak that get average nitrite content ( NO2 ) it started on Monday at Deli river 0,0281 mg/L; Percut river 0,0293 mg/L, on Tuesday at Deli river 0,0132 mg/L; Percut river 0,0174 mg/L, on Wednesday at Deli river 0,0193 mg/L; Percut river 0,0294 mg/L, on Thursday at Deli river 0,0133 mg/L; Percut river 0,0177 mg/L, on Friday at Deli river 0,0278 mg/L; Percut river 0,0300 mg/L, on Monday at Deli river 0,0197 mg/L; Percut river 0,0276 mg/L. The result of the research could be seen that nitrite content (NO2 ) for both of river are still safe used by society because if compared by standard water river water have no sample passing quality standard 0,06 mg/L according to Govermant Regulative No 82 of 2001.
