The Test Content of Heavy Metal Elements Fe, Pb, Cu and Cr in Tukad Badung Water, Dauh Puri Kauh Village by Atomic Absorption Spectrophotometry (AAS) Method
Research has been carried out to test the content of heavy metal elements in Tukad Badung water, Dauh Puri Kauh Village using the Atomic Absorption Spectrophotometry (AAS) method. This study aims to determine the content and levels of heavy metals Fe, Pb, Cu, and Cr in badung water. The AAS analysis was carried out at the Joint Laboratory of the Faculty of Mathematics and Natural Sciences, Udayana University. The results of the analysis show that Tukad Badung water, Dauh Puri Kauh Village contains heavy metal elements Fe, Pb, Cu and Cr and the concentrations are respectively 0,4616 ± 0,2378 mg/L, 1,8068 ± 0,7051 mg/L, 2,3035 ± 2,883 mg/L, and 1,9215 ± 0,0766 mg/L. Based on the Regulation of the Minister of Health of the Republic of Indonesia Number 416/MENKES/PER/IX/1990 concerning Clean Water Quality Requirements, the permissible quality standard for copper and iron heavy metals is 1 mg/L while the quality standard for lead and chromium heavy metals is 0,05 mg /L. This indicates that the Fe content is still below the threshold while the Pb, Cu and Cr metals in the water of Tukad Badung, Dauh Puri Kauh Village have exceeded the threshold.
