Analisa Kadar Nitrat (NO3 -) dan Nitrit (NO2 -) untuk Pengujian Air Limbah Industri dengan Metode Spektrofotometri varian/secomam pada Btklpp Kelas 1 Medan

Abstract

Sources of pollution may be industrial wastes or non-industrial waste in the form of liquid cair.Limbah dumped into the river, if excessive can cause damage lingkungan.Salah the chemical substances contained in waste water are nitrate (NO3) and nitrite (NO2). Nitrate (NO3) and nitrite (NO2) is a chemical compound that is toxic to the environment. In this analysis determined the levels of nitrate and nitrite in industrial waste water. From the analysis that has been done shows for the concentration of nitrate (NO3) yaitupada sample code 751 / AL = 0.5mg / l; 752 / AL = 16.2 mg / l; 753AL = 0.7 mg / l; 754 / AL = 0.1 mg / l; 756 / AL = 0.5mg / l, where the data obtained Conforms KEPMELNH-51 / menl / 10/1995 with standarissasi quality standard that is 20 mg / l. while the levels of nitrite (NO2) is the sample code 619 / AL = 3,3515mg / l do not Conforms KEPMELNH-51 / menl / 10/1995 and code samples 620 / AL = 0,1915mg / l; 621 / AL = 0.0461 mg / l; 622 / AL = 0,2036mg / l, where the data obtained Conforms KEPMELNH-51 / menl / 10/1995 with standarissasi quality standard that is 20 mg / l.
