عنوان انگلیسی Removal of Cyanide from Water and Wastewater Using Nanocrystalline ZnO/NiO Mixed Metal Oxide Powder
چکیده انگلیسی مقاله Increased demand for commodities as a result of the growing population has sped up industrialization. As a result of the expansion in industrial setups, there has been an increase in the generation of industrial waste. By polluting the water, air, and soil, these industrial pollutants seriously harm the ecosystem. Cyanide is one of the most significant environmental contaminants found in the sewage of various industries, and it can pollute water supplies in ways that are hazardous to both humans and the environment. There are numerous strategies to remove cyanide from aqueous media, however the majority of them are expensive. Consequently, this study’s objective is to remove cyanide utilizing nanocrystalline ZnO/NiO mixed metal oxide powder (ZnO@NiO). The influence of the adsorbent, initial cyanide concentration, contact time, and pH were evaluated in discontinuous phase for the removal of cyanide from aqueous media utilizing ZnO@NiO nanocrystals under varied conditions. Adsorption equilibrium were investigated in this study. The results of the study showed that the removal efficiency increases with the increase in retention time and the amount of adsorbent. The maximum amount of cyanide removal was obtained at pH = 10, retention time of 90 minutes, cyanide concentration of 2.5 mg/liter, and the adsorbent weight of 1 g, which was more than 98%.
