Research On Magnetium Magnetiteite Processing Technology And Quality Control Methods And Discuss About Processing Principle

Based on the systematize arrange of ancient and modern literature and investigation about Magnetium Magnetiteite, reveals the mainly quality problem of Magnetium Magnetiteite decoction pieces, epurate the common technology of calcining and quenching. Optimization experiment and evaluation of comprehensive index were made on process of preparing and quality control method.The purifying process of Magnetium Magnetiteite sifted 10 mesh was determined; take the content of iron, the release of Fe ion, the content of As and Pb for indexes, the calcining and quenching technology of Magnetium Magnetiteite was determined by single factor experiment and orthogonal test. The process was proved rational and feasible by verification and amplification test. The processing mechanism of Magnetium Magnetiteite was comprehensive and multi-angle discussed by the changes of trace (major) elements content, thermal analysis, infrared spectrum analysis and powder x-ray diffraction, while pharmacodynamic study was taken on water-decocted liquid and powder of Magnetium Magnetiteite and calcined Magnetium Magnetiteite from mind-tranquilizing, hypnosis, hemostasis and coagulation. The experiment proved that the content of principal component-Fe and majority of trace (major) element were obviously increased.After calcining and quenching, the powder x-ray diffraction of calcined proved that compared with Magnetium Magnetiteite, calcined Magnetium Magnetite produce a new Fe2O3 phase, the hardness was decreased, the texture become crisp, the content of toxic elements such as As,Pb etc were decreased, the dissolved content of the principal component-Fe and majority of trace (major) element were increased, then provide the basis for the processing mechanism of Magnetium Magnetiteite according to pharmacodynamics and physical chemical properties.Take amplification experiments of the processing technology for five producing area's ten batch, and the morphological identification, qualitative identification of Fe salt and powder x-ray diffraction were made on the samples. Make inspection about the contents of impurity and heavy metals as As,Pb,Cd, and made a relevant limit standard; Determine the content of Fe and the release of Fe ion, and the determination of the Fe ion release from Magnetium Magnetiteite and calcined Magnetium Magnetiteite was established. The quality control method of Magnetium Magnetite and calcined Magnetium Magnetite were established preliminary.
