Arsenic removal from aqueous solution using pyrite

摘要: Abstract Arsenic is one of the major pollutants and a worldwide concern because its toxicity chronic effects on human health. This investigation presents results arsenic adsorption onto four adsorbents such as pure pyrite, waste dried pyrite ground pyrite. The findings show that addition 5 g/L into solution proved high removal efficiency, with ability to reduce concentration As(V) in aqueous from an initial value 10 mg/L 10 μg/L at pH 5. range 4–6 for effective adsorb solution. It found oxidation particle size has big influence removal. Following adsorption, separation adsorbent liquid phase was achieved using flotation flocculation methods. Both methods were be removing loaded Test confirmed containing process water sample remove arsenic. 15 g/L provided 99% decreased received 38.5 mg/L 0.03 mg/L. High uptake capability cost-effectiveness make it potentially attractive
