Abstract

Bio-adsorptions are the most important water treatment products in the world for research in water treatment and the environment, thanks to their effectiveness, simplicity of manufacturing, profitability and low cost compared to other adsorbents. In this context, the present review aims to direct researchers interested in bio-sorption towards derivatives of plant materials and agricultural waste, which present more advantages, such as competitive efficiency, renewal of the raw material, possibility regeneration of the adsorbent several times by a simple treatment, and contribution to sustainability. And in the same context, this review organizes bio-adsorbents derived from plant material into four categories (raw, chemically treated, biochar, activated carbon), depending on the type of treatment of the raw material, and the degree of effectiveness, and presents the most recent examples.
