Cost-effective green synthesis and characterisation of arsenotungstate nanoparticles: enhanced sorption of Pb²+, antioxidant and photocatalytic properties with non-isothermal decomposition kinetics

Environmental context This work presents a synthesis of arsenotungstate nanoparticles and emphasises the significance of removing toxic pollutants in wastewater, as well as its applications for health and environmental benefits. Our study highlights the ecological and human health applications. Sorption behaviour and the importance of arsenotungstate-based nanomaterials revealed that it is a good adsorbent for toxic metals in wastewater treatment. The process and our work’s novelty, rigour and significance will make a strong contribution to environmental effects.
