Description
Summary:The determination of Silicon (Silica) in materials using the Molybdenum blue reaction was studied. The UV-Visible spectrophotometer scanning for the silicon molybdenum blue reaction was studied between a wavelength of 400nm and 800nm. The instrumental analytical procedure applied consists of four basic parts: the sample pretreatment, the instrument adjustment, the calibration and measurement and the calculations. The instrument was optimized using standard solution of KMnO^sub 4^ with conventional calibration method applied. The performance characteristics of the spectrophotometer at a wavelength of maximum absorption (λ^sub max^) of 825 ± 5nm for the silicon-molybdenum blue analysis are observed. The procedure was applied to amorphous silica produced from glass sand and the findings were observed to correspond with existing standard.
