"羟基萘酚蓝CAS:63451－35－4   英文名称:Hydroxynaphthol blue   规格：金属滴定指示剂   包装：1克      储存条件： RT

用途： 金属滴定指示剂，用于碱土金属离子, 稀土金属离子的检测

介绍： HNB是钙的金属指示剂，碱土金属离子、稀土金属离子、铀离子的比色试剂。HNB易溶于水和乙醇，HNB的水溶液在pH 7－12时呈蓝色，pH >13时呈红色，在pH 10且有钙离子存在时呈粉红色。碱土金属离子和稀土金属离子的检测范围分别为1－600 ppm和1－300 ppm。复合物的波长是650 nm。HNB也被用于UO2(II)的检测。据报道，HNB的质子解离常数为pKa4＝6·44, pKa5=12·91 (?=0·1，24℃)。"
