At pH9.5 nickel reacts with 2-(6-bromo-2-benzothiazolylazo)-5-diethyIatnino-phenol (Br-BTAE) in the presence of Tween-80 and sodium lauryl sulfate to form a red-violet complex which has an absorption maximum at 540nm (e2.5×10~5). Though this is also the absorption maximum of the reagent, yet the reagent will readily decompose at 40~50℃ within 20 min. The reagent blank is low and the error is negligible. Beer's law is obeyed for 0.01~0.125μg nickel in a 1mL solution. The composition of the complex was found to...

At pH9.5 nickel reacts with 2-(6-bromo-2-benzothiazolylazo)-5-diethyIatnino-phenol (Br-BTAE) in the presence of Tween-80 and sodium lauryl sulfate to form a red-violet complex which has an absorption maximum at 540nm (e2.5×10~5). Though this is also the absorption maximum of the reagent, yet the reagent will readily decompose at 40~50℃ within 20 min. The reagent blank is low and the error is negligible. Beer's law is obeyed for 0.01~0.125μg nickel in a 1mL solution. The composition of the complex was found to be Ni/Br-BTAE=1:2 by the continuousvariation method. This method can be applied to the determination of nickel in electroplating waste-water and in copper-aluminium alloy and steel samples after extraction with dimethylglyoxime. The results of the analysis agree with that from AAS and dimethylglyoxime method.

在Tween-80和十二烷基硫酸钠存在下,当pH为9.5时,镍(Ⅱ)与2-(6-溴-2-苯骈噻唑偶氮)-5-二乙氨基苯酚反应,形成红紫色配合物;它在540nm处有最大吸收,其摩尔吸光系数(ε)为2.5×10~5L·mol~(-1)·cm~(-1)。试剂Br-BTAE在此波长下亦存在最大吸收;但于40~50℃加热20分钟,可显著分解,因而空白降低,误差可忽略。在1mL溶液中含0.01~0.125μg镍时遵循比尔定律。配合物的组成为Ni/Br-BTAE=1∶2(连续变更浓度法)。此法可测定经丁二酮肟萃取后的电镀废水、铜合金、铝合金及几种钢样中的镍含量,分析结果与原子吸收法及丁二酮肟法的符合。
