我们曾报导了PVC膜四碘络铋离子选择电极的研制。现又研制了铋(Ⅲ)-溴,铋(Ⅲ)-氯的络阴离子PVC膜选择电极。本文比较了三种铋(Ⅲ)-卤素络阴离子选择电极的主要性能,并对络阴离子电极配位体的选择条件及阳离子的干扰规律进行了讨论。
We have previously reported the development of PVC membrane bismuth ion selective electrode. Now developed a bismuth (Ⅲ) - Bromine, bismuth (Ⅲ) - chlorine anion PVC membrane selective electrode. In this paper, the main properties of three kinds of bismuth (Ⅲ) -halogenide anion selective electrodes were compared. The selection conditions of the ligands of the anionic anion electrode and the interference of the cations were also discussed.
