In this study, three different waste biomass (soy waste biomass, mustard waste biomass and rapeseed waste biomass) resulted after oil extraction, were used as biosorbents for the removal of some heavy metal ions (such as Pb(II), Cd(II) and Zn(II)) from aqueous media. The biosorptive performances of each waste biomass were evaluated as a function of metal ions concentration in aqueous solution and contact time, and the obtained experimental results were modeled using Langmuir isotherm models and pseudo-second order kinetics model. The experimental values of the biosorption capacities have shown that all studied waste biomass retain significant quantities of heavy metal ions, in a relative short time, and can be a promising alternative biosorbents in the wastewater treatment systems. Analyzing the obtained experimental results it can be observed that the mustard waste biomass has the best biosorptive performances in the removal processes of heavy metal ions. Consequently, samples of industrial wastewater, with a concentration of each metal ion (50 mg/L), were contacted with this biosorbent and some important parameters related to water quality were determined according to standardized procedures.
