    Also these magnetic materials were assessed as matrices for the immobilization of invertase via covalent binding. Möss spectra of the magnetic composites performed at K showed a mixture of magnetite and maghemite about equal proportion in the mMMT, and a pure magnetite phase in the sample mDE. These results were verified using XRD.
