摘要
研究了在常压、温度303.15 K下,利用阿贝折光仪测定乙醇-水,甲醇-水以及甲醇-乙醇三个双液体系的折光率,并采用MATLAB建立了双液系折光率-组成关系模型。结果表明,折光率可快速鉴别甲醇和乙醇,而且利用拟合的关系模型可较精确地确定甲醇含量。
Taking advantage of Abbe refractometer to determine refractive index of three twin-fluid systems which were ethanol-water,methanol-water and methanol-ethanol under normal pressure,303.15 K,and the component relationship model of the twin-fluid system was established using MATLAB.The result indicated that refractive index can be quickly used to identify whether ethanol solution contained methanol,and can determine the methanol content more accurately by the model.
