Abstract

Analysis of nitrite content in well water and piping water that has been boiled is carried out on samples taken in one of the houses in the Tegal Arum area, Mojosongo, Surakarta. This analysis was conducted at the Laboratory of the University of Setia Budi. The purpose of this analysis is to determine there or not the content of nitrites in well water and piping water that has been boiled repeatedly, if there is the content of nitrite in the piping water and well water, then is there any difference in the nitrite content of the sample before boiling with sample after boiling. Analysis of nitrite in the piping water and well water that has been boiled in the first 10 minutes, second 10 minutes, and third 10 minutes is using visible spectrophotometry at a wavelength of 360 nm, with the addition of a solution of 1naftilamina, sulfanilic acid and nitrite standard. The addition of this solution shows a reddish indigo colour in the well water sample and piping water sample. Based on the analysis result have been obtained, nitrite level found in piping water before boiling at 192.8 ppm and the well water at 193.4 ppm. Nitrite levels in piping water sample, the first stew had level of 237.2 ppm and the second stew had level of 252.7 ppm, while nitrite levels in well water sample, the first stew had level of 216.1 ppm and the second stew had level of 255.5 ppm, this suggest that the levels of nitrite has increased compared with before boiling. Nitrite levels in the third stew, the piping water have a level of 222.6 and the well water had level of 230.0 ppm, this suggest that the third stew has decreased level of nitrite. Keywords: Nitrite, well water, piping water, visible spectrophotometry.
