Optimasi Digesti Asam Pada Analisis Merkuri (Hg) Dalam Sedimen Dengan Menggunakan Teknik Vapor Generation Accessory-Atomic Absorption Spectrophotometer (VGA-AAS)

Abstract: Kadar logam Hg di lingkungan perairan berada pada konsentrasi rendah, yaitu kisaran satuan µg/L. Dengan konsentrasi yang rendah tersebut, maka diperlukan tahapan analisis yang sesuai untuk memaksimalkan hasil analisis. Tahapan analisis logam ini termasuk di dalamnya adalah proses digesti. Digesti adalah proses perombakkan matriks sampel dari senyawa-senyawa yang berbentuk logam organik menjadi logam anorganik yang bebas dengan menggunakan asam kuat baik tunggal maupun campuran. Digesti merupakan tahapan paling… Show more

“…The determination of the precision value is carried out by measuring the instrument response to Pb and Cd metals at a measured concentration of 1; 3; and 5 ppb. Measurements were taken 3 times using AAS and UV-Vis and the average value was calculated with the Relative Standard Deviation (% RSD) equation [12]. The following equation to determine the precision value of %RSD:…”
