原位ATR-IR光谱实时研究DKDP的结晶过程
In Situ ATR-IR Investigation on the Crystallization of DKDP Crystals
摘要
Abstract
The crystallization of KH2-x Dx PO4 ( DKDP) crystals with different deuterium contents ranged from 0 to 99％ were investigated in solution by Attenuated Total Reflectance Infrared ( ATR-IR) spectroscopy. The ( H2 PO4 -) 1-x ( D2 PO4 -) x ionic groups were characterized by theυ1 ( PO4 ) andυ3 ( PO4 ) vibrations. The intensity changes of theυ1 ( PO4 ) vibration peaks and the broadened width changes of theυ3 ( PO4 ) vibration peaks indicate that the ( H2 PO4 -) 1-x ( D2 PO4 -) x concentration increases with the measurement time increases. Besides, the appearance ofδ( P—O…H/D—O—P) vibration illustrates the formation of ( H2 PO4 -) n-x ( D2 PO4 -) x clusters, which can be confirmed as growth unite. The intensity changes of the H—O—H and D—O—D vibration at the wavenumbers from 1448 cm-1 to 1653 cm-1 can illustrate the un-uniform distribution of deuterium con-tents in DKDP crystallization process.关键词
