Isolation and characterisation of cellulose from cortex, pith and whole of the Pennisetum purpureum: Effect of sodium hydroxide concentration

In this study, the potential of cellulose isolation from the cortex, pith, and whole of the Pennisetum purpureum stem was explored. The cellulose was extracted using 4, 8, 12, 16, and 20% concentration of alkali followed by 1.7% concentration of sodium chlorite. The cortex and pith of Pennisetum pur...
