摘要

目的：分析纳米雄黄酸水飞品（Realgar nanoparticles processed，NRPP） X射线衍射（XRD）图谱和拉曼光谱的图谱特征，并比较雄黄炮制前后晶形结构的异同。方法：采用X射线衍射法和拉曼光谱法对6批雄黄生品，6批雄黄水飞品，6批纳米雄黄酸水飞品进行测定，确定各样品的物相组成及晶形结构成键情况。结果：XRD分析表明雄黄生品和雄黄水飞品均为β-As4S4，纳米雄黄酸水飞品中NRPP1，NRPP5及NRPP6批次为β-As4S4，NRPP2，NRPP3及NRPP4批次为β-As4S4和α-AsS的混合体。拉曼光谱分析表明雄黄生品、雄黄水飞品和纳米雄黄酸水飞品均在360~362，342~344，185~187，164~166 cm-1等波数位置出现了特征性较强的拉曼振动峰。结论：X射线衍射技术与拉曼光谱法相结合，能较好地反映出纳米雄黄酸水飞品的特征吸收峰，可用于纳米雄黄酸水飞品的鉴定与分析。雄黄经常规的水飞法炮制未造成晶型结构的变化，而经纳米化并酸水飞后晶形结构则发生改变。

Abstract

Objective: To analyze X-ray diffraction (XRD) and Raman spectrum of Realgar nanoparticles processed(NRPP)

and compare the differences of crystal structures before and after processing.Method: XRD and Raman spectrum were applied to measure the phase composition and shape of crystal structures of 6 batches of Realgar

6 batches of water processed Realgar and 6 batches of NRPP.Result: XRD analysis showed that Realgar and water processed Realgar were β-As4S4; NRPP1

NRPP5 and NRPP6 batches were β-As4S4; while NRPP2

NRPP3 and NRPP4 batches were the mixture of β-As4S4 and α-AsS. Raman spectroscopy analysis indicated that the strong characteristic Raman peaks appeared at the wave number locations of 360-362

342-344

185-187

and 164-166 cm-1 for Realgar

water processed Realgar and NRPP.Conclusion: Combined X-ray diffraction with Raman spectrum can better reflect the characteristic absorption peak of NRPP and can be applied for the identification and analysis of NRPP. There is no change on the crystal structure of Realgar normally processed by water

but the structure is changed by nano-acid water processing.
