Analisis Kuantitatif Besi (Fe), Seng (Zn) dan Mangan (Mn) Dalam Air Sumur Dengan Metode Spektrofotometri Serapan Atom
TL;DRAbstract
An analysis have benn done to determine the concentration of Iron (Fe), Zinc (Zn) and Manganese (Mn) in ground water sample which was measured by Atomic Absorption Spectrophotometer using wet digestion method with concentrated HNO3 addition as solvent and to forming an acid condition. Then the absorbantion measured at wavelength (λ) = 248,3 nm for Iron; 213,9 nm for Zinc and 279,5 nm for Manganese. The result of analysis showed the concentration of Iron, Zinc and Manganese were: 0,3621 mg/l; 0,0117 mg/l and 3,1567 mg/l. Based of the result analysis showed the Iron and Zinc concentration in ground water sample which was analyzed were lower than maximum limit standard in PPRI No. 82. 2001, and the concentration of Manganese was higher than maximum limit standard which was allowed in PPRI No.82 .2001 Universitas Sumatera Utara
