Large-scale surfactant releases into the environment, both direct and indirect, can have detrimental effects on human health and the environment. Surfactants should therefore be eliminated from water before it is released into the environment or made available to the general population. In this study, silver nanoparticles were used to remove sodium lauryl sulfate (SLS), an anionic surfactant. This work used extract from Brassica oleracea (broccoli) to create silver nanoparticles in an environmentally friendly manner. Additional AgNPs were created by employing the precipitation process in an aqueous solution containing metallic precursor sulfates. Using scanning electron microscopy, or SEM, the broccoli silver nanoparticles were characterized. 200 nm is the SEM size for B-AgNPs. Ag-NPs’ chemical characteristics were observed by an FTIR (Fourier Transmission of Infra-Red) investigation. By adjusting various factors such as duration, dosage, pH, beginning concentration, and temperature, it was discovered that the maximum percentage elimination of B-AgNPs was 94%. According to the experimental findings, the adsorption rate rose as contact duration and adsorbent dosage increased whereas it fell as temperature and the initial sodium lauryl sulfate concentration increased. At a pH of 6, the highest rate of adsorption is seen. The batch experiment findings showed that B-AgNPs had an equilibrium time of 25 minutes. The elimination of surfactants has been examined using pseudo first-order and pseudo-second order kinetics. The Langmuir and Freundlich isotherm models were used to mathematically model equilibrium data.
