Analisa Kadar Nitrat (NO3) dan Nitrit (NO2) dari Campuran Limbah Laboratorium dan Domestik Dengan Menggunakan Spektrofotometer Dr 2000/2010 pada Balai Riset Standardisasi Industri Medan

Abstract

Source of its(the contamination cans be in the form of domestic waste and or domestic xenon waste which is in the form of liquid. Liquid waste which thrown to river, if abundant can cause area damage. One of consisting in chemistry matter ineffluent is Nitrat ( NO3) and Nitrit ( NO2). Nitrate ( NO3) and Nitrit ( NO2) be a chemistry compound having the character of toxic to area. At this analysis determined nitrate rate and nitrite at laboratory waste mixture and domestic. From analysis which has been done obtained [by] result for rate Nitrat ( NO3) be 0,2034 mg/L ; 0,0805 mg/L ; 0,07363 mg/L while for rate Nitrit ( NO2) be 0,0055 mg/L ; 0,0049 mg/L ; 0,1499 mg/L. From the result is known that laboratory waste mixture and domesticdoesn't pass quality standard which has been specified by The Minister of Environment No 51 The year 1995 namely 20 mg/L for Nitrat ( NO3) and Nitrit( NO2) 1 mg/L.
