Compared with the previous method, the improved route can provide directly a spheroid form of immobilized lipase particles of which the size can be controlled by adding non-ionic surfactants during the preparation process so as to increase the recovery rate of enzyme as well as decrease the external diffusional restriction which can diminish the enzyme activity. The improved method can also alter the hydrophobicity and microstructure of the immobilized enzyme matrix by changing the molar ratios of different alkoxyl silanes so as to enhance the enzyme activity by a"surface active effect"and eliminating the internal diffusional restriction.

There exists isomorphous replacement in the rutile structure, and the most prominent feature is the average content of oxides, being 1.22%, 0.39%, 0.35% and 0.22% for V 2O 5, Fe 2O 3, ZnO and CuO respectively. They substitute Ti 4+ in octahedra. The valence of V is 5, and its polyhedron is trigonal bipyramid, which causes the lattice distortion, breaks the raw octahedron symmetry into square bipyramid, and produces the microstrains in the structure.
天然含钒金红石平均含V2O5可达1.22%,Fe2O30.39%,ZnO0.35%,CuO0.22%,这些金属离子可替代八面体中Ti^4 。V以5价形式存在,配位多面体呈三方双锥,其在晶格内部对Ti的替代导致晶格畸变,打破了配位多面体原有的八面体对称而呈四方双锥的几何形态,并产生结构微应力。
