“…Biosorbents have several other strengths, such as cost-effectiveness, high surface area and environmental friendliness (El-Kalliny et al 2024; Guo et al 2024). Various resources, such as cotton, nanocellulose, wood, and chitosan can be used to produce biomass materials (Nie et al 2023; Peng et al 2023). Furthermore, biomass can be derived from sources like agricultural waste, excess food, and animal husbandry waste (Wang and Li 2023), The cost-effectiveness, high accessibility, biodegradability, ease of modi cation, and renewability of biomass sorbents provide numerous advantages compared to other materials (Ma et al 2023;Yardımcı and Kanmaz 2023;Zhang et al 2023a).…”

This study focuses on the development of a wood sponge (WS) modified with MnO2 nanorods (MnO2/WS) from balsa natural wood, as an abundant environmental-friendly raw material, to adsorb organic solvents, oils, and heavy metal ions from water. The MnO2/WS composite exhibits an exceptionally low density of 0.014 g cm− 3 and a high porosity exceeding 97%. MnO2/WS demonstrates successful sorption-desorption cycles over 20 iterations. Zeta potential analysis reveals the negative charge (-22.31 mV) of MnO2 nanorods at pH 4.68, underscoring their affinity for adsorbing positively-charged heavy metal ions commonly found in industrial effluents. Moreover, WS exhibits exceptional mechanical robustness, enduring 1000 stress-strain cycles with high shape recovery, ensuring its durability under operational conditions. Data above proved several strengths for MnO2/WS, such as cost-effective production process, high reusability, remarkable sorption capacities for carbon tetrachloride and soybean oil at 29.56 and 17.65 times its mass, respectively, efficient performance, and the capability to produce potable water from real industrial effluents position MnO2/WS as an ideal solution for mitigating water crises.
