Magnetic activated @entity505 composite ( @entity68518 /AC, MACC) was prepared by a co-precipitation-calcination method. The MACC consisted of porous micro-particle morphology with homogeneously distributed @entity68518 and possessed high magnetic saturation moment (8.1emug(-1)). The performance of MACC was evaluated as catalyst and regenerable adsorbent via @entity15909 ( @entity18809 , @entity43992 (  )) activation for @entity6693 (MB) removal. Optimum @entity68518 /AC w/w ratio was 1:1.5 giving excellent performance and can be reused for at least 3 cycles. The presence of common inorganic ions, namely Cl(-) and @entity8326 did not exert significant influence on MB degradation but humic acid decreased the MB degradation rate. As a regenerable adsorbent, negligible difference in regeneration efficiency was observed when a higher @entity43992 (  ) dosage was employed but a better efficiency was obtained at a lower MACC loading. The factors hindering complete MACC regeneration are MB adsorption irreversibility and AC surface modification by @entity18809 making it less favorable for subsequent MB adsorption. With an additional mild heat treatment (150  C) after regeneration, 82% of the active sites were successfully regenerated. A kinetic model incorporating simultaneous first-order desorption, second-order adsorption and pseudo-first order degradation processes was numerically-solved to describe the rate of regeneration. The regeneration rate increased linearly with increasing @entity43992 (  ):MACC ratio. The MACC could potentially serve as a catalyst for @entity18809 activation and regenerable adsorbent.
