Biochar prepared by co-pyrolysis of nano-zero-valent iron and sewage sludge (nZVIS was used to remove As(Ⅴ) from aqueous solution. When the initial pH was 2, the initial As(Ⅴ) concentration was 20 mg L-1, the dose of nZVISB was 10 g L-1, the contact time was 24 h, and the adsorption temperature was 298K, the removal efficiency of As(Ⅴ) was greater than 99%. The isothermal removal of As(Ⅴ) followed the Freundlich model better, and the maximum adsorption capacity of As(Ⅴ) was 60.61 mg g-1. The removal process of As(Ⅴ) could be bette
