Penentuan Kadar Mn (Mangan) pada Air Baku dan Air Reservoir Secara Spektrofotometri di PDAM Tirtanadi Medan

Abstract

Was done determination attempt titrates manganese on default water and reservoir water at PDAM Tirtanadi Field by use of DR's spectrophotometer tool 5000. With indicator increase 1 - (2 - pyridil azo)-2 - naftol (PAN), will form orange's color that denotes to mark sense manganese content. Of data attempt result that acquired on default water from PDAM Tirtanadi Field which is,0,045 mg / l,0,056 mg / l,0,000 mg / l,0,174 mg / l,0. 081 mg / L.Dan datas of waters already at o which is, 0,008 mg / l, 0,017 mg / l, 0,005 mg / l, 0,017mg / l, 0,004 mg / l. Base rule about drinking water requisite is named that drinkings water maximal rate be 0,1 mg / l meanwhile maximal fresh water 0,5 mg / l. So that water qualities standard pock water because don't exceed bounds already being determined.
