Penentuan Kadar Timbal (Pb) pada Air Minum Isi Ulang dengan Metode Spektrofotometri Serapan Atom di UPT. Laboratorium Kesehatan Provinsi Sumatera Utara

Abstract

Testing has been carried out regarding the quality of refillable drinking water around the city of Medan Pancing. By using the Atomic Absorption Spectrophotometry (AAS) method is principled on the absorption of light by atoms. The atoms absorb the light at a certain wavelength, where the wavelength used is 383.3 nm. Sample preparation using HNO, and analyzed with chemical parameters. Laboratory test results show that all drinking water samples are negative. In the SSA test Metal levels contained in refill drinking water for lead metal (Pb) in sample 5619 = - 0.1139mg / L sample 5620 = - 0.1075mg / L sample 5621 = - 0.1032mg / L sample 5622 = - 0.1032mg / L sample 5023 = - 0.093mg / L sample 57 = - 0.0959mg / L sample 58 = - 0.1118mg / L sample 59=-0.0967 mg/L sample 60 = - 0.9462mog / L The nine samples did not exceed the threshold and still meet the standards set by the Minister of Health of the Republic of Indonesia through Permenkes No.492/Menkes/Per/IV/2010 regarding Drinking Water Quality requirements, which is a maximum of 0.01 mg/L
