Abstract: MANGOILSTEEN is an agricultural waste adsorbent which is utilized to remove several types of dyes from aqueous solutions by adsorption. A highly revolutionary project, this product will contribute in eradicating negative toxins being thrown by the tons into the sea every day. Current dye adsorbers are purely chemical and not safe towards the environment. Combining mangosteen pericarps and waste cooking oil produces an adsorbent that can directly adsorb any dyes in universal solutions. The present work highlights the facile synthesis of combining agricultural waste and free fatty acid from waste cooking oil as a green sorbent for the efficient removal of dyes from aqueous solutions. In order to assess the performance of this new synthesized sorbent, screening tests will be performed on various type of dyes. The effectiveness of present sorbent in adsorbing of dyes from aqueous solutions will be studied as a function of agitation time, adsorbent dosage, initial dye concentration and pH. Moreover, the reusability of the sorbent will be investigated, as it is one important factor to prove that the developed sorbent is economical and practical. We believe that, this low-cost sorbent, with their sustainable sources and excellent biodegradable nature will be an innovative and competitive bio-product for the removal of dyes from environment samples.
