摘 要:采用紫外可见分光光度法分析添加剂高锰酸钾溶于醇基燃料溶液中时的实验现象,并采用E-pH图法分析实验结果。研究结果表明:混合溶液颜色随着时间的延长逐渐发生变化,吸光度也随之改变;锰元素在醇基燃料溶液中呈现不同价态,证实KMnO4不能稳定地与甲醇燃料共存,因此影响燃料的发热值。
Abstract: The experiment phenomenon was tested by ultraviolet-visible spectrophotometer when KMnO4 exists in the methanol fuel. And the results were analyzed using E-pH diagram. The results show that the absorbance changes when the color of the mixed solution changes gradually and KMnO4 can not coexist with methanol fuel steadily and thus it affects the calorific value of methanol fuel.
