一种乙二醇苯醚含量的测定方法
摘要：
本发明公开了一种乙二醇苯醚含量的测定方法，包括步骤为：配制不同浓度的乙二醇苯醚标准溶液，以水作为空白对照，对标准溶液测定波长270nm处的吸光度值，以吸光度值和标准浓度为坐标建立坐标系，绘制标准曲线；对乙二醇苯醚待测溶液测定波长270nm处的吸光度值，将吸光度值利用标准曲线进行线性回归，得到待测溶液的浓度。通过上述方式，本发明的乙二醇苯醚含量的测定方法是用紫外分光光度法能快速测定溶液中乙二醇苯醚的含量，该方法测定时间短，结果准确有效，实施容易，不需要借助昂贵的实验仪器和试剂，成本较低，易在中小型实验室中普及使用。
摘要（英）：

The invention discloses a method for testing the content of glycol phenylate. The method comprises the following steps: preparing glycol phenylate standard solutions of different concentrations, with water as blank control, testing the absorbance values of the standard solutions at the wavelength of 270nm, establishing a coordinate system with the absorbance values and standard concentration as coordinates, drawing a standard curve, testing the absorbance values of the glycol phenylate standard solutions at the wavelength of 270nm, and performing linear regression on the absorbance values by virtue of the standard curve so as to obtain the concentration of the solution to be tested. In such a mode, the method for testing the content of glycol phenylate is to rapidly test the content of glycol phenylate in a solution by an ultraviolet spectrophotometry method. The method is short in testing time, accurate and effective in result, easy to perform, free of expensive experiment instruments or reagents, relatively low in cost and easy to popularize and used in middle and small laboratories.
