Abstract:
This article discusses the quantitative analysis of common acid adical ions such as Cl-, SO2-4 nd acetic cid ions in micro olution from fluid inclusions by laser Raman spectrometry. The relationship between some Raman parameters, such as Raman strength, width of half height, peak area and so on, with corresponding oscillating molecules or ionic groups were studied and was used in estimating the molecule or ion concentrations in the solution. The results from the study show that the parameters of characteristic peaks of H2SO4 and acetic acid have good linear relationship with their concentrations and WA1/WA2 and WH1/WH2, which reflect the change of the Raman peaks of electrolyte solutions, can be used for estimating the concentration of Cl-. The regression equations etween concentration and Raman parameters of each acid solution are fitted by multiple statistics method.
