Mitigating Cesium Contamination: Harnessing the Potential of Nigella Sativa for Water Remediation

Abstract

                Contamination of water resources with cesium poses a significant environmental threat, necessitating effective remediation strategies. This manuscript explores the potential of Nigella Sativa, commonly known as black seed, as a novel and sustainable solution for mitigating cesium contamination in water. Through a series of controlled experiments, the adsorption and removal efficiency of Nigella Sativa for cesium ions were investigated. Our findings reveal promising results, highlighting the ability of Nigella Sativa to effectively reduce cesium concentrations in water from 0.0 to 64 % at constant pH for water and changing the concentration of nano nigella sativa (NSN) concentration. But when the pH of the water is changed from 3 to 11 and the NSN concentration value is fixed at 5 mg, the efficiency of removing cesium from polluted water will change. It was found that the best removal was at the pH value of 5. The unique chemical composition of Nigella Sativa seeds, rich in active compounds, demonstrates its potential as a natural and cost-effective material for water remediation. This research contributes to the development of eco-friendly approaches for cesium decontamination, with implications for environmental and public health. Further exploration of the mechanisms involved and the scalability of this remediation method is recommended for future applications.
