Water hyacinth is a fast growing noxious weed in the tropical countries. A significant amount of ethanol can be produced from sugar obtained by saccharification of water hyacinth substrate. The present work emphasizes the studies on sulphuric acid pretreatment of water hyacinth for production of xylose. The xylose yield has been studied with the parametric variation of soaking time, treatment time, treatment temperature and the concentration of sulphuric acid. The maximum value of xylose yield obtained is around 70.2 mg/g of dry water hyacinth, when hydrolyzed with 5% sulphuric acid at a temperature of 130℃, soaking time of 45 min and treatment time of 10 min. The yield corresponds to the initial loading of 2.5%. The yield drops drastically on increasing the temperature above this point which may be due to the degradation of xylose. A correlation of xylose yield with soaking time, treatment time, treatment temperature and acid concentration has also been determined during this study.
