Production of Silica from Mustard Husk Ash

Abstract

India is the agricultural dominated country where 75% if its population depends upon the agriculture for production of wheat, groundnut, mustard, cotton Tea, Coffee, pulses, soya and Jute.  According to the central organizationof oil trade (COOTI), 89.5 lakh ton mustard seed was produce during 2020-2021.The MustardHusk residue easily available in the states which are producing Mustard crop. The mustard seed cellulose after extracting the oil used as the cattle feed supplement which increase the milk extent .The Mustard husk use as the industry fuel for heating the water in boilers for power generation.Agriculturalwastes like mustard husk, rice husk, Palm husk and fly husk have the excellent raw material for producing the silica (SiO₂).Silica is the Major constituent of Mustard husk ash(MHA) by which it is very become economical for producing silica from MHA. Here we are producing the silica by Citric acid leaching process of mustard husk ash at optimum conditions 800⁰C and 50 minutes of reaction time & concentration of citric acid above 2%. Theproduce silica has more than 80-85% purity
