Synthesis of Detergent from Rice Husk

The project’s primary goal is to create a detergent powder from paddy husk ash. mesoporous silica is used as a raw material in a variety of applications, including detergents and soaps, as well as a refractory component. Sodium silicate is formed by reacting rice husk ash (RHA) with aqueous NaOH, and silica is precipitated from the sodium silicate via acidification. In these experiments, approximately 90% of the silica contained in RHA was converted into sodium silicate in an open system at temperatures around 100°C. The results showed that silica derived from RHA is mesoporous, with a large surface area and a small particle size. Rice husk is typically mixed with coal and used to fire boilers. As a result, carbon particles are frequently found in RHA. The carbon already present in RHA was used to create activated carbon embedded on silica. This carbon has a high adsorption capacity. The filtrate is made up of sodium phosphate. Therefore, the use of high concentration of Sodium and completely ashed rice rusk will result in a better Sodium silicate quality for detergent production.
