A carboxymethylcellulose (CMC) nanohybrid composition comprising carboxymethylcellulose loaded with metal nanoparticles, such as silver nanoparticles (AgNPs), iron nanoparticles (FeNPs), or silver nanoparticle-doped iron nanoparticles (AgNPs@FeNPs). These compositions can be used to remove contaminants, such as 2,4-dinitrophenol, from wastewater. The compositions are low-cost, eco-friendly, and highly efficient for 2,4-dinitrophenol removal due to the high surface area-to-volume ratio and super catalytic effect to remove 2,4-dinitrophenol. The results indicate that the performance of fabricated AgNPs@Fe@CMC nanohybrids is relatively high and suitable compared to commercial materials.
