To ensure the protection of public health and environmental integrity, while also meeting effluent regulation standards, it is critical to treat leachate due its composition hazardous substances before introduced into environment. Pollution from characterized by several indicators, including COD, BOD5, conductivity, pH, presence various ions such as ammonium, nitrite, nitrate, chloride, orthophosphate. This research examines adsorption properties natural bentonite clay Nador, located in eastern Morocco, for efficacy removing nitrite synthetic leachates. We present outcomes experiments utilizing eradicate these nitrogen-based artificial leachate, using UV spectroscopy measurement ion concentrations after adsorption. Additionally, study evaluates efficiency adsorption, identifying optimal amount required effective pollutant reduction. Our results demonstrate that, following a 24-hour mixing period, rates were roughly 48%, 40%, 85% at 35°C, 15%, 25% 25°C, respectively. These findings suggest that modulation agitation duration temperature can significantly improve efficiency, with elevated temperatures facilitating shorter reaction times higher nitrogen ions. Ultimately, confirms potential an medium removal contaminants landfill offering promising approach enhancing sustainability.
