Uji Presisi Kadar FE Pada Asi Metode Spektrofotometri Serapan Atom

One of the nutrients that babies need is iron (Fe). Iron content can be measured by atomic absorption spectrophotometry (AAS). This method often used because it simpler, more accurate and has high precision. study was to determine levels precision examination in breast milk using AAS. The this research preparation samples, tools, materials, manufacture a standard solution (Fe), calculation value milk. According findings, three test groups' average Fe level 1.1486 mg/L. study's run based on repeatability. In study, conducted measuring groups samples ten times. repeatability declared acceptable comparing CV obtained with CV-Horwitz, if %CV less than then acceptable. Based measurements have been made, (%) group A 7.0690, B 9.0686, C 7.9807. These results indicate % which smaller CV-Horwitz. Depending findings validation technique for calculating AAS satisfies standards approved value.
