Industrial and urban development is increasing water pollution in Cameroon. Urgency to search for inexpensive depollution methods and easy implementation. The objective was to remove heavy metals (Cu2+, Zn2+) from wastewater by adsorption on rice huks (RH). RH were characterized before moving to simultaneous adsorption of these two ions and optimization.The analysis indicaded that, the point of zero charge is 8.7; for the pH value less than 8.7, the biosorbent surface is positively charged and for pH value higher than 8.7, the biosorbent surface is negatively charged. The biosorbent iodine number is 1560.87±1 mg/g, it means that, the biosorbent is constituted in majority of microspores. Furthermore, the specific surface of biosorbent is 104.45±1m2/g, it is five times as big than untreated rice husk obtained by Elie and al., (2019). Infrarouge spectrum present ether and aromatic functions. The central composite design was used to determine the weight of factors, the interactions between factors and optimal zone of simultaneous adsorption of the Cu (II) and Zn(II) ions. The analysis of experimental design indicates that, the factors which control the adsorption of the two ions.
