“…Most of the adsorption studies have been focused on untreated plant/agricultural wastes such as orange peel [2], rice husk [3], oil palm trunk fiber [4], Aspergillus fumigatus [5], wheat straw [6], durian (Durio zibethinus Murray) peel [7], Eucalyptus bark powder [8], almond shells [9], clay materials [10], pomelo (Citrus grandis) peel [11], Luffa cylindrica fibers [12], Parthenium biomass [13], castor seed shell [14] and granular kohlrabi peel [15]. Recently, an extensive list of adsorbent literature for dye removal has been compiled by Allen and Koumanova [16].…”
