Analysis And Verification Of Microstructure Of Salt Solution System

Solution system of inorganic salt solution and solvent have been studied, mainly aim has been focused at studying salvation phenomenon of solution, and the change of the solvent molecular of saline solution.Research methods including infrared spectrum and fluorescence spectra have been applied,at the same time theoretical calculation has been used,which discussing concentration of solution temperature and ion influenced the microstructure of solution system at molecule level.As a result of solvent response between ion and molecule,it would produce new molecule cluters in solution after inorganic salt added in organic solvent; The proportion of organic solvent molecule with solvent response and the cation and anion structure is changed when the concentration and temperature changed; In the double solvent system of N, N-dimethylformamide or ethanol,new clusters with fluorescence attributive would produce.By means of structure optimization, it would indicate that fluorescence strength of ion cluster formed by salvation concerned with the charge of cationic and size of radius.
