“…The survey spectra for the WSwinter HULIS sample reveal the presence of 4 major elements: carbon, oxygen, nitrogen, and sulfur (Figure 4a). Atomic compositions for each sample were calculated using narrow-scan peak areas and the appropriate sensitivity factors for each element (Chastain 1992;Atzei and Rossi 2004). Carbon and oxygen clearly dominated the chemical composition.…”

Humic-like substances (HULIS) constitute a class of organic compounds identified in atmospheric samples that influence many properties of aerosols in the atmosphere. In this study, 6 HULIS samples were isolated from atmospheric total suspended particle (TSP) samples collected at 3 locations in Guangzhou of China, 1 each in summer and winter. On the basis of analyses by elemental analyzer, more detailed chemical species of elements were explored by proton nuclear magnetic resonance ( China (No. 40975090, 40830745, and 40505026) and the Guangdong Natural Science Foundation (9151064004000008). This is contribution No. IS-1414 from GIGCAS.

“…Different from the techniques used to determine bulk composition, XPS is a highly surface sensitive technique with a sampling depth of ∼10 nm, which can determine the chemical composition of the outermost surface of airborne particles (Atzei and Rossi 2004). A comparison of the elemental compositions obtained by XPS and elemental analysis will yield information on the heterogeneity of particles.…”

“…In addition, the use of XPS core-level peaks to derive chemical structure information of organic solids by fitting peak intensity and position features, is the standard XPS application (Briggs and Seah 1990;Monteil-Rivera et al 2000;Olivella et al 2002a,b;Paoletti et al 2003;Qi et al 2006). Therefore, the XPS technique has been used to investigate the elemental composition and chemical states of aerosol surfaces (Albers et al 2000;Hutton and Williams 2000;Zhu et al 2001;Lazzeri et al 2003;Paoletti et al 2003;Atzei and Rossi 2004;Qi et al 2006;Gilham et al 2008). For example, Zhu et al (2001) utilized XPS and other superficial analytical techniques to characterize the PM2.5 sample collected from Salt Lake City, Utah, USA.…”

X-ray photoelectron spectroscopy (XPS) is a powerful techniquefor determining the surface chemical composition of atmospheric particles. In this article, we employed XPS to study atmospheric particles collected from Guangzhou city in typical sites and seasons. The results showed that the weight percentage of carbon, oxygen, nitrogen, and sulfur were about 70.5-87.1%, and these species dominated the surface structure of the particles independent of the collection site and season. Inorganic elements including Si, Na, Ca, Cl, Fe, K, Al, and Cu were also found on the particle surfaces. The high-resolution XPS spectra revealed: (1) High aromatic and aliphatic C-H, and other oxidized carbons were found on the surface of particles. (2) The nitrogen species were characterized by pyridinic, pyrrolic/amide, quaternary type nitrogen functionalities, and nitrate groups, indicating that inorganic and organic N species are both important components of N-containing particles. (3) Sulfate and sulfone groups were also present on the surface and were important components. The oxidized groups of C, N, and S were higher in winter samples, consistent with the monsoon weather of Guangzhou in winter, which is favorable for the formation of oxidized species. A comparison between total and surface analyses showed that the surface of particles was relatively high in organic carbon, NO

Both conservation and intervention methods must be compatible with each other and appropriate for the original building materials. Therefore, the characterization of historic building materials is indispensable for investigating chemical composition, micro-structure and morphological features to study the current condition, environmental influence and change mechanism due to natural aging or man-made decay processes. Given the great variety of chemicals which can be analyzed, complex problems related to architectural heritage materials are investigated via optimized methodologies. Among the existing techniques, optical microscopy (OM) is an inexpensive and dominating tool to obtain preliminary information on complex samples. Atomic force microscopy (AFM) can provide real three-dimensional topographies showing sample surface properties. Electron microscopes combined with energy dispersion X-ray analysis (EM-EDX) are the instruments specifically developed to acquire images of target materials at high magnification. Infrared and Raman spectroscopies are frequently used to characterize inorganic and organic compounds. Thermal analysis can rapidly and accurately measure changes in crystalline structure, dehydration and decomposition. X-ray based technologies have a wide range of applications as follows. X-ray fluorescence (XRF) is one of the most frequently used techniques for elemental analysis. X-ray diffraction (XRD) is a fast and inexpensive technique for the characterization of man-made and natural materials. X-ray photoelectron spectroscopy (XPS) is applied to quantify the valence and electronic levels of specific elements. X-ray absorption spectroscopy (XAS) is a powerful technique for detecting the electronic structure of matter. UV-visible (UV-vis) spectroscopy is also of great importance in architectural heritage, which can reveal different physicochemical mechanisms causing color. Laserinduced breakdown spectroscopy (LIBS) can effectively eliminate the pollution on the surface and detect the internal elements of the target material. Ion beam analysis can quantify trace elements with high sensitivity. Mass-based techniques are mainly applied to identify unknown organic substances at the molecular level. This review describes some classical applications of individual techniques and provides scientific support for scientists and engineers to make decisions in the context of architectural heritage.
