Tóm tắt

This research aimed to extract lignin from rice straw and reveal the pH value of diluted acid at which the most effective yield of lignin was precipitated. In this study, rice straw obtained from local fields in the An Giang province of Vietnam and sodium hydroxide 2 M was employed to extract lignin from rice straw.Hydrochloric acid was used to adjust the sample pH values to be in the range of 1.5-3.5...
