利凡诺制剂的含量测定方法已见报道的有氧化还原法、容量沉淀法、分光光度法等。各种方法除存在本身的局限性外,无法测出分解前后本品的含量变化是最大的不足。笔者根据利凡诺本身具有荧光的特性,拟定了用荧光光度法测定利凡诺含量的方法。结果较为满意,现报道如下。一、仪器。分光光度计751型(上海分析仪器厂),荧光光度计930型(上海第三分析仪器厂)。
The assay for rivanol formulations has been reported for redox, volumetric, spectrophotometric and the like. In addition to the existence of various methods of its own limitations, can not be measured before and after decomposition of the content of this product is the biggest change. According to the characteristics of rivanol itself with fluorescence, the author developed a method for the determination of rivanol content by fluorescence spectrophotometry. The results are more satisfactory, are reported below. First, the instrument. Spectrophotometer type 751 (Shanghai Analytical Instrument Factory), fluorophotometer type 930 (Shanghai Third Analytical Instrument Factory).
