Abstract
Ca/Mg/Al/Fe layered double hydroxides (LDHs) were synthesized through coprecipitation using steelmaking slag as raw material. The structural morphology of Ca/Mg/Al/Fe LDHs was characterized, and results revealed a well-defined shape with obvious intercalated structure under pH 12 at 150 °C. The presence of acetate groups in the LDHs interlayer was further confirmed. Ca/Mg/Al/Fe LDHs was used to absorb methyl orange from aqueous solution. The results demonstrate that the as-prepared Ca/Mg/Al/Fe LDHs exhibit excellent absorption capacity (58.18 mg/g) towards methyl orange in aqueous solutions when the initial methyl orange concentration was at 50 mg/L This result is practically significant for absorbent selection to control environmental pollution.
