A comparative study on physical characteristics of cellulose isolated from various sources of rice husk

Cellulose is the biomass that is most easily found in plants, bacteria, and marine organisms.However, it is not found in pure conditions in nature and is always bound to other materials such as lignin, hemicellulose, silica, wax, and ash.Rice husk is an abundant agricultural waste and has high cellulose content from different rice husks such as Pusa Rh-10 (92), Dwarf (22-70), Parvati (27-16), Sona and BPT that have been successfully isolated.The cellulose obtained from different sources was characterised by various physical, micromeritic properties and percent yield.Kawakita plots were used to observe micromeritic properties.The percentage yield and other properties were found to be dependent on the source of cellulose.The % yield was found to be from 33% to 60%.The flow properties such as carr's index, bulk density and hausner ratio were found to be dependent on the source of cellulose and the particle size of cellulose.Among the varieties used in this investigation, 92 varieties showed good flow property and produced a high yield of cellulose.
