Kinetic adsorption results indicated good agreement with pseudo first-order-kinetic model (R = 0.998) and the maximum adsorption capacity calculated by Langmuir isotherm of Mg/Al/Bi MMO was 202.2 mg/g, which is higher than that of Mg/Al layered double oxide (LDO) (161.0 mg/g) and bismuth oxide (57.5 mg/g).
