Validation Method on Determination of Chemical Oxygen Demand Using Indirect UV-Vis Spectrometry

Abstract: The validation method for determination of chemical oxygen demand (COD) with indirect UV-Vis spectrometry have been done. This method enable to easily perform highly sensitive, considerably faster and easier, and minimize the use of digestion solution. This method is the development of standard method of COD determination by closed reflux using UV-Vis spectrometry so it requires the method validation stage. The validation is used to ensure linearity, limit of detection, limit of quantification, precision, and … Show more

“…Nilai MDL telah memenuhi semua syarat kebeterimaan dengan nilai % RSD 10,52%, % Recovery sebesar 100,20 %, nilai signal to noise sebesar 9,50 dan nilai 10% spike sebesar 16,20. Berdasarkan hasil penelitian menunjukkan bahwa pengujian COD pada low concentration dan high concentration memiliki sensitivitas yang baik [9][14].…”
