摘要
本文研究了新试剂 Ｍ Ｂ Ｔ Ａ Ｑ （甲氧基苯并噻唑偶氮－ ８－ 氨基喹啉） 与钯的显色反应。在 Ｃ Ｔ Ｍ Ａ Ｂ 存在下， 钯与试剂在弱碱性介质中形成稳定的蓝色配合物， 钯浓度在０－ ２０μｇ／２５ｍ ｌ范围内， 符合比尔定律。该方法用于废水中微量钯的测定， 结果较满意。
The colour reaction of palladium with 5-(6-methoxy-2-benzothiazoleazo)-8- aminoquindine(MBTAQ) has been investigated It is shown that in the presence of the ationic surfactants cetyltrimethylammonium bromide(CTMAB) and borax buffex solution,palladium forms a blue coloured 1:1 complex with MBTAQ Beer's law is obeyed for palladium in the range 0-20μg/25ml The method has been applied to the spectrophatometric determination of trace palladium in waste water
