Description |
Silicon is an essential element found in cereals, fruits, vegetables pasta, rice, etc. Rice husk ash is one of the most silica rich raw materials after complete combustion among the family of agro wastes. For the preparation of pure activated silica rice husk are now widely used as raw material. Rice husk ashes are now used by various industries for different applications due to its important properties. The exact quantity of silica in the rice husk ash is therefore essential to know before further research. Keeping these facts an attempt has been made to determine the silica content by titrimetric method followed by quantification of uncertainty budget in four different variety of rice husk ash. The major sources of uncertainty in the measurement have been identified as contributions from repeatability, standardization of sodium hydroxide, titration, weight of the sample taken, volume measurement by volumetric flask, burette, pipette, weighing balance etc. All major sources of uncertainty have been identified and combined following the EURACHEM guidelines.
