The rate of the coordination reaction between divalent metal ions and murexide in a water - in - oil microemulsion was determined by spectrophotometric technique to study the transport of the metal ions entrapped in the organogel formed by cationic surfactant cetyltrimethylammonium bromide
以微乳液中二價金屬離子與紫脲酸胺之間的配位反應為指示反應,採用分光光度技術,研究了金屬離子在由陽離子表面活性劑十六烷基三甲基溴化胺構建的微乳凝膠中的傳質問題。The effect of hexadecy pyridine choride on the dissociation constants of thymol blue bromide, cresol red, o - ckesolphthalein and thymol blue, as well as their the colour - changing ranges were studied by spectrophotometry
探討了表面活性劑氯化十六烷基吡啶形成的膠束對溴百里香酚藍、甲酚紅、鄰甲苯酚酞和百里香酚藍離解反應的離解常數的影響,同時,也研究了該表面活性劑對上述四種酸堿指示劑變色范圍的影響。The experimental results indicated that the colour - changing ranges got narrow, and the titration accuracy was increased when an appropriate surfactant micellar solution was chosen as a titration medium
實驗結果表明,表面活性劑存在時,酸堿指示劑的離解平衡及其變色范圍將發生改變,選擇適當的膠束溶液作為滴定介質,可以擴大酸堿指示劑的應用范圍,同時也可以提高滴定的準確度。
