Adsorption kinetics of immobilized laccase on magnetically-separable hierarchically-ordered mesocellular mesoporous silica

The adsorption kinetics of laccase immobilization on magnetically-separable hierarchically-ordered mesocellular mesoporous silica (M-HMMS) as the support was studied. Past studies on the immobilization of laccase through adsorption have gradually increased, but the kinetics and mechanism of laccase...
