ANALISIS PERBEDAAN KADAR NITRIT SUMUR GALI TPA DENGAN PENAMBAHAN DAN TANPA Na2EDTA

Abstract

The nitrite-in-water examination should be noted for the existence of the iron metal
cation (Fe+), in the water cation samples can affect the test result of nitrite levels at the
time of reading in the UV-Vis spectrophotometer. Na2EDTA Additions function to bind
the metal found in the sample as well as chemical disorders as in the presence of
chemical formation that can lead to not perfecting the association of substances to be
analyzed so as to influence measurements at the time of reading in Spectrophotometer.
The nitrite rate assessment was measured using the UV-Vis spectrophotometer method
with a wavelength of 534 nm. The measuring rate range is 0.01 mg/L to 1.00 mg/L. There
are differences in nitrite-level test results on well-dug water around the TPA with
addition and without Na2EDTA using Uv-vis spectrophotometry.
