Abstract
Water hyacinth (Eichornia crossipes) is a type of weed in the Liliopsidae class, which grows in swamp, lake, dam or river having slow water stream. Water hyacinth has various shape and size, depending on its geographical grow area. Water hyacinth has a good adsorption property, which is able to adsorb heavy metals and sulfides. Besides, it contains protein, cellulose at higher content than non cellulosic material in the form of lignin, ash, lipids, and others. This research was purposed to investigate the possibility of water hyacinth char to reduce Chrom (VI) content in electroplating industries waste water and to study the adsorption kinetics of Chrom (VI) ions on the water hyacinth char particles.
