Bamboo charcoal (BC) as an environmentally friendly and low-cost material receives widespread attention. Recently, much attention has been focused on the use of BC as adsorbent to treat wastewater. This paper provides an overview of the adsorption of organic contaminants in solution by using BC. The sorption behaviors of BC with various organic pollutants, and the kinetic model adopted to explain the adsorption rate of organic pollutants from aqueous solution were also reviewed. The adsorption capacity, the isotherm model, and several key factors such as modification, surface area, are discussed in this paper. Possible improvement of BC to treat organic contaminants in aqueous solution is also proposed.
