在有阳离子表面活性剂(CTMAB)存在的条件下,于 pH 5.7～6.5范围内,5-(6-溴-2-苯骈噻唑偶氮)-8-羟基喹啉(简称6-Br-BTAQ)与铝形成稳定的紫红色络合物.其最大吸收波长为460 nm,表观摩尔吸光系数为2.5×10~4L·mol~(-1)·cm~(-1).络合物的组成为 Al∶ R=1∶3.～10μg/25ml 的铝服从比尔定律.
In the presence of a cationic surfactant (CTMAB), 5- (6-bromo-2-benzothiazolylazo) -8-hydroxyquinoline ) Formed a stable purple complex with aluminum, the maximum absorption wavelength was 460 nm, and the apparent molar absorptivity was 2.5 × 10 -4 L · mol -1 cm -1. The composition of Al: R = 1: 3 ~ 10μg / 25ml of aluminum subject to Beer’s law.
