利用表面敏感光谱（如x射线光电子能谱（XPS））识别氯硝石（Pb5(PO4)3Cl）的能力对于理解自然和工程系统中的铅和磷酸盐地球化学非常重要。我们利用XPS研究了来自德国Kanderbach的一种结构良好的六方晶体样品在空气暴露的断裂表面上的初级光电子结合能。用Perkin Elmer物理电子5200c谱仪采集了一般巡天光谱和高分辨率光谱。利用非稳态碳作为能量参考。报道了pb4f7 /2、pb4f5 /2、p2p3 /2、p2p1 /2、p2s、o1s、cl2p3 /2和cl2p1 /2光电子的电荷修正结合能。这些光谱可用于识别矿体、土壤和磷酸盐稳定废物系统中的环境重要的磷酸铅矿物，如氯硝石。
The ability to identify chloropyromorphite (Pb5(PO4)3Cl) using surface-sensitive spectroscopies such as x-ray photoelectron spectroscopy (XPS) is important in understanding lead and phosphate geochemistry in natural and engineered systems. We have used XPS to study the binding energy of primary photoelectrons from an air-exposed fracture surface of a well-formed hexagonal crystal sample from Kanderbach, Germany. General survey and high resolution spectra were collected using a Perkin Elmer Physical Electronics 5200 C spectrometer. Adventitious carbon was used for energy referencing. Charge corrected binding energies for the Pb 4f7/2, Pb 4f5/2, P 2p3/2, P 2p1/2, P 2s, O 1s, Cl 2p3/2, and Cl 2p1/2 photoelectrons are reported. These spectra are useful in identifying environmentally important lead phosphate minerals such as chloropyromorphite in ore bodies, soils, and phosphate-stabilized waste systems.
