溴邻苯三酚红与铁显色反应的研究

Study of Color Reaction of Iron(Ⅲ) with Bromopyrogallol Red

研究了在非离子表面活性剂OP存在的条件下．在醋酸-醋酸钠介质中，溴邻苯三酚红与铁（Ⅲ）的络合显色反应．建立了测定铁的新方法．此方法用于水中铁（Ⅲ）的测定．效果良好．

In the presence of emulsifier OP, this paper studies the color reaction of iron(Ⅲ) with bromopyrogallol red in HAc-NaAc medium, and sets up a new method to determine iron(Ⅲ). This method has been applied to the determination of micro-amount of iron(Ⅲ) in waste water with satisfactory results.
