Water hyacinth plants were tested for its chemical composition
(hemicellulose, cellulose, lignin, ash) using thermogravimetric
analysis . 5 mg of water hyacinth samples were pyrolyzed in nitrogen atmosphere at tem-perature 25 until 800C, with increment of 10C/min. The gener-ated weight loss vs. temperature curve was then examined to
determine the water hyacinth’s chemical compound based on the
degradation of individual components at specified temperature
range . Hemicellulose, cellulose and lignin content of water hyacinth sample used in this
experiment are listed in
