Penentuan Kadar Nitrat(No3 -) dan Nitrit (No2 -) pada Air Mineral Isi Ulang dan Air Bersih Secara Spektrofotometri di Laboratorium Dinas Kesehatan Medan

Abstract

Had done an analisyst determining value of Nitrate (NO3 -) and Nitrit (NO2 -) in refill mineral water and clear water accordance with spectrofotometry with long wave 410 nm for nitrate (NO3 -) and 543 nm for nitrit (NO2 -). Maximum value of nitrate (NO3 -) in drinking water and clear water according to Regulation of Minister of Public Healthy R.I. Government namely 10 mg/L and maximum value of nitrit (NO2 -) in drinking water and clear water namely 1,0 mg/L. Result that had got, for analisyst of refill mineral water value of nitrate (NO3 -) 1st example namely 0,7 mg/L, 2nd example namely 1,9 mg/L, 3rd example namely 1,5 mg/L, 4th example namely 1,3 mg/L. Value of nitrit (NO2 -) that get from 1st example namely 0,01 mg/L, 2nd example namely 0,09 mg/L, 3rd example namely 0,02 mg/L, 4th example namely 0,01 mg/L. Analisyst for clear water value of nitrate (NO3 -) that get from 1st example namely 0,7 namely 0,7 mg/L, 2nd example namely 0,9 mg/L, 3rd example namely 0,4 mg/L, 4th example namely 1,7 mg/L. Value of nitrit (NO2 -) that get from 1st example namely 0,02 mg/L, 2nd example namely 0,38 mg/L, 3rd example namely 0,20 mg/L, 4th example namely 0,01 mg/L. From the result that get can make conclusion that refill mineral water and clear water still down of maximum value that had be decision Minister of Public Healthy R.I. Goverment. This is indicate that the refill mineral water and clear water had analysted can to comsume and can use.
