物理化學(xué)性質(zhì)
外觀性質(zhì)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(shí)呈藍(lán)色，pH >13時(shí)呈紅色，在pH 10且有鈣離子存在時(shí)呈粉紅色。堿土金屬離子和稀土金屬離子的檢測(cè)范圍分別為1-600 ppm和1-300 ppm。復(fù)合物的最大波長(zhǎng)是650 nm。HNB也被用于UO2(II)的檢測(cè)。據(jù)報(bào)道，HNB的質(zhì)子解離常數(shù)為pKa4＝6.44, pKa5=12.91 (µ=0.1，24℃)。
