This study presents the synthesis of zeolite-NaX from rice husk using the hydrothermal method.The synthesized material exhibited the formation of zeolite-NaX as confirmed by X-ray diffraction (XRD) analysis.The substance was subjected to further modifications through the silver (Ag 0 ) nanoparticles and surfactant sodium dodecyl sulfate (SDS) to further investigate the adsorption properties of mercury and dyes in water.As a result of the ion exchange reaction and reduction by silver nanoparticles (AgNPs), the particle size was 15-16.4nm.Cationic methylene blue and mercury ion (Hg 2+ ) adsorption onto unmodified and modified zeolites was studied using a batch equilibration method.The sorbent modified with silver nanoparticles was investigated for its ability to purify water from mercury ions (Hg²⁺), resulting in an increased sorption capacity from qmax = 136.9 to 285.7 mg g⁻¹.The possibility of removing dyes from an aqueous medium at a neutral pH was also studied.The sorption capacity increased from 9.21 to 13.48 mg g⁻¹ when the SDS modified the sorbent.During 24 hours, preliminary results showed that the removal of mercury ions from the solution ranged from 27 to 76% and the removal of methylene blue from 18 to 87% of the initial concentration.
