摘要

• Magnetic chars are prepared and characterized using aerobically digested and undigested sewage sludge. • Langmuir–Freundlich model is used to simulate their adsorption isotherm of 1,2,4-Acid. • Different adsorption mechanism may be correlated with their chemical composition and textural properties.
