Maize straw core absorbing material and preparing method thereof

Abstract

The invention discloses a maize straw core absorbing material and a preparing method thereof, which includes the following steps: the maize straw core is crashed to be steamed and boiled in high pressure, sucked, filtered and washed in a mixed solution comprising high boiling-point alcohol and alkali; the filtered slag is oxidized by the oxidizing agent H2O2 and rapidly cooled; the absorbing material is obtained after refrigeration and drying. The preparing method of the invention uses the maize straw core as the raw material for preparing the absorbing material which effectively absorbs neutral protease and maltogenic amylase but does not inactivate the enzyme, sufficiently uses the natural resource, simplifies the preparing method and satisfies the requirements of sustainable development.

Description

technical field [0001] The invention relates to an adsorption material and a preparation method thereof, in particular to a corn stalk wick adsorption material and a preparation method thereof. Background technique [0002] As a special biocatalyst, enzyme has the advantages of high selectivity and catalytic efficiency, mild reaction conditions, and adjustable catalytic activity. The high activity and high selectivity of enzymatic reactions have been used in organic synthesis for asymmetric synthesis, synthesis and resolution of optically active compounds and natural compounds. However, free enzymes are very sensitive to the environment, and are not stable enough in strong acids, strong alkalis, high temperatures, high ion concentrations, and some organic solvents, which can easily lead to denaturation of enzyme proteins, thereby reducing or even losing their catalytic activity. At the same time, the free enzyme reaction is not easy to separate from the substrate and produc...

But 30% of these stalks are used as agricultural fuel, 25% are used as feed, 2-3% are used as raw materials for sideline production, 6-7% are directly returned to the field, and 35% of the remaining 220 million tons of stalks have not been rationalized. use

As a fuel, affected by consumption concepts and lifestyles, straw resources are completely in a state of high consumption, high pollution, and low output. A considerable part of crop straws are discarded or directly burned, and have not been rationally developed and utilized.
