| 摘 要： | 本文通过多次试验，确定了荧光增白荆中三嗪杂质的测定方法。本方法采用液相色谱-质谱联用仪和红外光谱对标准样品进行了定性；使用液相色谱进行分离，用263nm波长进行检测，峰面积外标法进行定量。给出了定量方法的线性回归方程，回收率90％～110％，最小检测限0．005％。 |

A Study on Analysis Method of the Triazines in Fluorescent Brighteners |
|
| Abstract: | An analysis method of triazine impurities in fluorescent brighteners was determined by dozens of experiments. The standard samples were qualified by LC-MS and IR; the triazine impurities in fluorescent brighteners were separated by HPLC and were determined at wavelength 263 nm, and then they were quantified by peak area external standard method. The linear regression equation of the method was given, the recovery rate was 90% -110% and the detection limit was 0. 005%. |
