“…The different parts of fibrous plant-based biomasses, considered low-cost potential metal biosorbents, are leaves, stems, stalks, roots, bagasse, seeds, shells, peels, husks, bark, and fibers [ 46 , 76 , 77 ]. Various plant fiber-based biomasses have been widely used as natural materials, pretreated or chemically modified, for heavy-metal removal from aqueous media, including wastewater and aqueous solutions.…”

Mobilization of heavy metals in the environment has been a matter of concern for several decades due to their toxicity for humans, environments, and other living organisms. In recent years, use of inexpensive and abundantly available biosorbents generated from fibrous plant-based food-waste materials to remove heavy metals has garnered considerable research attention. The aim of this review is to investigate the applicability of using fibrous plant-based food waste, which comprises different components such as pectin, hemicellulose, cellulose, and lignin, to remove heavy metals from wastewater. This contribution confirms that plant-fiber-based food waste has the potential to bind heavy metals from wastewater and aqueous solutions. The binding capacities of these biosorbents vary depending on the source, chemical structure, type of metal, modification technology applied, and process conditions used to improve functionalities. This review concludes with a discussion of arguments and prospects, as well as future research directions, to support valorization of fibrous plant-based food waste as an efficient and promising strategy for water purification.

Polypropylene wastes were used to prepare carboxylated (CPP) and sulfonated (SPP) microparticles for the adsorption of Mn (II) from aqueous media. The microparticles derivatized with nitric or sulfuric acid were characterized in terms of their physico-chemical properties. The generated functional groups on CPP (–COOH and –NO2) and SPP (–COOH, –SO3H, and C = C) enhanced the adsorption of metal ions. The adsorption behavior of Mn (II) ions on the derivatized microparticles was studied under different conditions: Solution pH, polymer dose, contact time, initial concentration of Mn (II) ions, and temperature. Application of kinetics and equilibrium models to the data revealed that the adsorption processes followed pseudo-second order reactions and the Langmuir isotherm. SPP achieved a higher maximum adsorption capacity (9.15 mg g−1) than CPPs (5.51 mg g−1). Therefore, sulfonation was considered the most efficient approach to produce a suitable surface functionality for the removal of metal ions from aqueous solutions. However, thermodynamic studies showed that all adsorption processes are spontaneous and feasible (ΔG = − 1.32 and − 1.46 kJ mol−1 at 20 °C for CPP and SPP, respectively), which ensure the possibility of employing acid-derivatized PP microparticles for metal removal.
