| 摘 要： | 利用红外光谱法，选择合适话带，标准加入和吸光度比例法相结合对松香酸、液体石蜡混合物进行定量测定，克服了化学滴定法的不足与两组分难以分离的缺点，为准确定量高分子弹性体中添加剂成分开辟了一条新的途径。该方法用于弹性体中松香酸、液体石蜡测定，相对标准偏差分别为３．０２％和１．５５％，相对误差分别为１．３１％和０．４５％。

| Abstract: | By employing infrared spectroscopy, the mixture of rosin acid and liquid paraffin was quantitatively determined through the selection of appropriate band and the standard addition method in combination with absorbance single weighing. The shortcomings of chemical titration and the difficulty of separation of two components were overcame. A new way was opened up for the quantitative analysis the componentes of additives in polymer. This method is used to determine the rosin acid and liquid paraffin in the elastpmer, the relative standard diviation are 3. 02% and 1.55% respectively, the rlelative errors are 1. 31% and 0. 45% respectively. |
