六十年代以来,分析化学领域中表面活性剂的应用和研究工作取得了显著进展,尤其阳离子表面活性剂,非离子表面活性剂在胶束增溶分光光度法中应用最广。为寻求对显色反应有更强敏化作用,更高选择性的表面活性剂,作者在天津市轻工业化学研究所协助下,合成了两性表面活性剂,并已应用于光度分析中,如测定轻重稀土分量、合金中微量铝等,表现出高灵敏度、高选择性等优点,水溶性和稳定性也较阳离子表面活性剂为好。本文把两 Since the 1960s, remarkable progress has been made in the application and research of surfactants in analytical chemistry. In particular, cationic surfactants and nonionic surfactants have been widely used in micellar solubilization spectrophotometry. In order to seek a more sensitized and more selective surfactant that has a good color reaction, the amphoteric surfactant was synthesized with the assistance of Tianjin Institute of Light Industry and Chemistry and has been used in photometric analysis such as determination Light and heavy rare earth components, such as trace aluminum alloy, showing high sensitivity, high selectivity, etc., water solubility and stability than the cationic surfactant is better.
