A separation model of ionizable and neutral enantiomers with cyclodextrin-sodium dodecyl sulphate (SDS) micellar electrokinetic chromatography was established.
The enzymolysis effect of neutral protease, papain, pepsin, bromelin, flavourzyme and compound protease was studied respectively on the sleeve-fish protein.
The results have shown that the brown alundum coatings are high-class neutral refractory coatings and are used with success in iron and steel cast-ings.
