摘要:
The prolonged consumption of arsenic-contaminated water is linked to an elevated risk of cancer. As(III) in wastewater exhibits greater mobility, biotoxicity, and removal challenges than As(V). Acidic mine drainage (AMD) sludges are solid wastes produced by mining industry. In this study, a novel biochar modified with AMD sludge (AMDs@PB 2 ) was prepared via co-pyrolysis of AMD sludge and pine needles to remove As(III) from the solution. The effects of preparation conditions (pyrolysis temperature, raw material ratio) and environmental factors ...
