"羥基萘酚藍CAS:63451－35－4   英文名稱:Hydroxynaphthol blue   規(guī)格：金屬滴定指示劑   包裝：1克      儲存條件： RT

用途： 金屬滴定指示劑，用于堿土金屬離子, 稀土金屬離子的檢測

介紹： HNB是鈣的金屬指示劑，堿土金屬離子、稀土金屬離子、鈾離子的比色試劑。HNB易溶于水和乙醇，HNB的水溶液在pH 7－12時呈藍色，pH >13時呈紅色，在pH 10且有鈣離子存在時呈粉紅色。堿土金屬離子和稀土金屬離子的檢測范圍分別為1－600 ppm和1－300 ppm。復(fù)合物的波長是650 nm。HNB也被用于UO2(II)的檢測。據(jù)報道，HNB的質(zhì)子解離常數(shù)為pKa4＝6·44, pKa5=12·91 (?=0·1，24℃)。"
