The invention relates to a high voltage electric field effect color changeable material and a preparation method thereof. The high voltage electric field effect color changeable material comprises two parts, namely an inorganic material component I and an organic material component II; and the changeable material is green when not under the effect of voltage, and is red under the effect of high voltage electric field of more than 1000 V. The electric affected color changeable material prepared by the invention has good electrochemistry oxido-reduction reversibility; and the product made of the electric affected color changeable material has a short response time, with the color change being reversible and highly sensitive, has a certain memory storage function, has good chemical stability, thermal stability and an anti-solution corrosion property.

The invention relates to a biomass gasification catalytic cracking process and an integral gasification catalytic reactor. According to the process, the integral reactor of which the lower part is provided with a biomass gasification section and the upper part is provided with a tar catalytic cracking section is adopted; the biomass gasification section is a fluidized bed, air serving as a primary gasification agent is introduced from the lower part, biomass enters the reactor from the middle-and-lower part to perform oxido-reduction gasification reaction with the gasification agent at the temperature of between 600 and 750 DEG C to generate gas accompanied with tar; the gas accompanied with the tar enters the tar catalytic cracking section on the upper part, the tar catalytic cracking section is a fixed bed into which a tar cracking catalyst is filled, a secondary gasification agent is introduced from the lower lateral part for filling the tar cracking catalyst, and the tar is cracked and converted into small-molecular combustible gas in the tar catalytic cracking section at the catalytic cracking temperature of between 750 and 800 DEG C; and generated ash content is discharged from an ash discharge opening on the lower part of the reactor, and the gas is discharged from a gas outlet on the top of the reactor to enter the next process. By the biomass gasification catalytic cracking process, the problem that the tar is separated from flying ash difficultly in the biomass gasification process is solved, and the gasification efficiency is improved.

The invention relates to an economic method for removing chloride ions in a copper sulphate solution. The method comprises the following steps: adjusting a pH value and oxido reduction potential and adjusting copper sulphate with sodium carbonate and sodium sulfite to a reaction interval where Na2[CuCl3] can stable exist; carrying out heating, adding elemental copper powder, allowing Na2[CuCl3] in the solution and the elemental copper powder to undergo comproportionation so as to produce a white CuCl cuprous salt precipitate insoluble in water; and carrying out full cooling to separate cuprous salt sediment and the copper sulphate solution so as to obtain a dechlorinated copper sulphate solution. The method utilizes the characteristic that wet cuprous salt sediment is not stable under the condition of a high pH value to convert the wet cuprous salt sediment into dechlorinated copper residues consisting of CuO, CuCO3 and Cu(OH)2 and to return the dechlorinated copper residues into a system for reuse, and a produced sodium chloride solution has high concentration and can be directly used for evaporative preparation of industrial NaCl. The method is widely applicable to removal of chloride ions of various concentrations from high-concentration copper sulphate solutions; reagents added for reaction do not influence quality; except cost for heating, operation cost is negligible; and the method is economic and easily practicable.

The invention relates to a preparation method of amycin controlled-release chitosan nano particles with pH / oxido-reduction dual response. Thiolated chitosan, carboxymethyl chitosan, sodium tripolyphosphate, doxorubicin hydrochloride and hydrogen peroxide are taken as raw materials. The preparation method comprises the following steps: mixing a thiolated chitosans solution with a doxorubicin hydrochloride solution so as to obtain a solution I; mixing a carboxymethyl chitosan solution with a sodium tripolyphosphate solution so as to obtain a mixed solution II; dropwise adding the mixed solution I into the mixed solution II while stirring, controlling the dosage of carboxymethyl chitosan and thiolated chitosan, regulating the ph value of the solution to 6-8, performing ultrasonic blending, performing ion crosslinking and polymer condensing, then dropwise adding hydrogen peroxide into the system so as to finish oxidization crosslinking, performing room-temperature stirring reaction, separating products, and drying the products to obtain the amycin controlled-release chitosan nano particles with pH / oxido-reduction dual response. The amycin controlled-release chitosan nano particles with pH / oxido-reduction dual response is capable of escaping away from tumor cell endosome / lysosome, is capable of automatically regulating and controlling to realize cytoplast release based on unique microenvironments of tumor cells, improving the amycin medicine delivery efficiency and the medical effect, and has a favorable research and development application background in multiple aspects such as medicine and medical materials.
