Abstract:
This article reports the cellulose extraction protocol and the yield determination from spent lemongrass. Spent lemongrass, an industrial by-product is a rich source of cellulose. The present study was carried out to investigate the effect of alkaline treatment processing parameters like sodium hydroxide concentration, solution temperature and immersion time on spent lemongrass cellulose yield. Box behnken design was employed and response surface methodology was adopted for statistical modelling and optimization of NaOH solution concentration, solution temperature, and immersion time with an aim to extract maximum cellulose by eliminating lignin, hemicellulose and extractives. The optimum process conditions were 2.05 w% NaOH, 80 °C temperature, and 2.08 h of extraction time with a cellulose yield of 28.08%.
