In recent years, natural occurrences and human activity have led to the flow of toxins into water, including colors, pharmaceuticals, and heavy metals. This needs good water treatment to eliminate the detrimental impacts of dyes, drugs, and toxic heavy metals in water in order to provide clean water to the environment and households. This study focused on modified zeolite adsorbents for water treatment technologies that are successful in removing various colors, pharmaceuticals, and heavy metals. Adsorption is the most effective techniques for removing dyes, drugs, and heavy metals from the wastewater. This work is to examine the literature research and development of modified zeolite adsorbents for removing colors, medicines, and heavy metals from water, with a focus on adsorption capacity, influence of pH, isotherm and kinetic model, removal efficiency, and contact time.
