磁场对高锰酸钾溶液吸收光谱的影响

目的:研究了磁场对高锰酸钾(KMnO4)吸收光谱的影响.结果:KMnO4溶液整体磁化及以磁化水为溶剂的KMnO4溶液吸收光谱与原溶液有所不同,其最大吸收波长紫移,二者紫移程度不同,而且吸收峰处吸光度有所增加.在一定时间内磁化时间越长,吸收峰处吸光度增加越多,磁场强度越大对吸收曲线影响越显著.说明在磁场作用下,水分子及高锰酸钾结构及状态的改变对高锰酸钾吸收光谱有影响.

The Effect of Magnetic Field on Absorption Spectrum of Potassium Permanganate Solution

Objective: The effect of magnetic field on absorption spectrum of potassium permanganate solution have been studied. Results: The absorption spectrums of both the magnetized potassium permanganate solution and that dissolved in magnetized water are different from the original state. Their absorption wavelength at the crest are minished with defferent degree. Their absorbance at the crest increase. The influence is more distinct on absorbance curve with the stronger magnetic field, and the absorbance at the crest more increases with the longer magnetized time. It shows that the changes of the structure and state of water molecule and potassium permanganate in the magnetic field affect the absorption spectrum of potassium permanganate solution.
