The invention relates to an analysis and detection method of a prasugrel intermediate, which is used for 5-[2-cyclopropyl-1-(2-fluorophenyl)-2-oxoethyl]-5,6,7, 7A-Tetrahydrothieno[3,2-C]pyridin-2(4H)-one quality control, using octadecylsilane bonded silica gel as packing column (C18, 4.6×150mm, 5μm), Using phosphoric acid aqueous solution-acetonitrile or acetic acid aqueous solution-acetonitrile as the mobile phase, the detection wavelength is 220nm, and the reversed-phase high performance liquid chromatography is used for analysis and detection. The method of the invention has the following advantages: high separation degree, short analysis time, simple and convenient operation, stable and reliable analysis method.

A preparation method of an activated carbon modified material, comprising the first step of pretreatment of activated carbon, the second step of combined physical and chemical modification of activated carbon, and the like. The present invention adopts the high-temperature water vapor activation method combined with the chemical modification method to modify the pore structure and surface oxygen-containing groups of the pretreated activated carbon, and the prepared activated carbon modified material has an increased number of micropores less than 1 nm , the oxygen-containing groups on the surface are significantly reduced, and it has high-efficiency adsorption performance for methylene chloride under high water content conditions. The preparation process of the invention is simple, the amount of consumable materials is small, and the preparation conditions are mild. The prepared activated carbon modified material has the advantages of large micropore volume, good moisture resistance and stable adsorption performance, which can effectively weaken the influence of water molecules on the adsorption effect of methylene chloride, and make up for the adsorption of target organic compounds by porous carbon materials under the condition of high water content. Insufficient capacity.

The invention discloses a sludge pretreatment method based on a sulfonic acid porphyrin iron catalyst Fenton-like system, comprising the following steps: mixing the sulfonic acid porphyrin iron catalyst, methanol and hydrogen peroxide solution, stirring, and mixing the obtained The liquid is mixed with the sludge for hydrolysis treatment to complete the pretreatment of the sludge. The present invention is based on the sludge pretreatment method of the sulfonic acid porphyrin iron catalyst Fenton system, by first mixing and stirring the sulfonic acid porphyrin iron catalyst, methanol and hydrogen peroxide solution to generate a mixed solution containing high-valent iron species , and then mixed with sludge, using high-valent iron species to achieve effective treatment of sludge, has the advantages of low catalyst and oxidant consumption, mild reaction conditions, high treatment efficiency, good treatment effect, and good adaptability. The effect of resource utilization is of great significance, with high use value and good application prospect.
