The invention discloses a kind of carbon skeleton enhanced type porous-starch and preparation method thereof, the porous-starch the preparation method comprises the following steps: by starch in conjunction with transition metal ions, the starch with transition metal ions is handled with amylase by extrusion equipment later, the starch based porous materials of high-intensitive recombination structure are eventually formed, i.e., the described carbon skeleton enhanced type porous-starch.Present invention reduces the enzyme dosage of bioanalysis and action times, also it changes physical method to be only capable of as pretreated status, there is wide application prospect with substitution object and other medical treatment, chemical industry, environment and Material Fields in medicine controlled releasing, water pollution purification, embedding. |
