Abstract: The determination of themaximumadsorption capacity for a biosorbent is crucial to evaluate the adsorption performance. This parameter is usually obtained from the Langmuir isotherm because it involves very simple and low-cost procedures.Nevertheless, acquisition of adsorption isothermcan be very laborious.Multivariate optimization can be used to improve the determination of themaximumadsorption capacity. In thiswork, Central Composite Design (CCD) and Surface Response Methodology (SRM) are used for a reliable determination of maximum adsorption capacity of arsenic by a biosorbent of lettuce flour and the result was very close to the value obtained from the Langmuir isotherm.
