摘要

研究了酸性偶氮染料-磺偶氮和刚刚红-罂粟碱（1-（3,4-二甲氧基苄基）-6,7-二甲氧基异喹啉）在聚氨酯泡沫上固相萃取离子对的pH、相接触时间和组分比的函数关系。基于偶氮染料对罂粟碱离子对的吸附，利用漫反射光谱法和比色法在吸附剂表面进行检测，建立了测定药物配方中罂粟碱的方法。

Determination of Papaverine as Ion Pairs with Anionic Azo Dyes through Solid-Phase Extraction Using Polyurethane Foam

The solid-phase extraction of ion pairs formed between acidic azo dyes—Sulfonazo and Congo Red—and papaverine (1-(3,4-dimethoxybenzyl)-6,7-dimethoxyisoquinoline) on polyurethane foams is studied as a function of pH, phase contact time, and component ratio. A procedure is developed for determining papaverine in pharmaceutical formulations based on its adsorption as ion pairs with azo dyes, followed by detection on the adsorbent surface using diffuse reflectance spectroscopy and colorimetry.
