Integrated Analysis Scheme of Fluoride in Oilfield Chemicals

In this study, an integrated rapid analysis scheme for inorganic and organic fluoride components in oilfield chemicals were established based on visual colorimetry method. Fluoride components were extracted from different types of oilfield chemicals under microwave and then pretreated by microwave digestion to convert the organic fluoride components into inorganic fluoride components. Organic and inorganic fluoride components were rapid analyzed using visual colorimetry. The scheme realized the integrated rapid detection of inorganic and organic fluoride components for different oilfield chemicals including water-soluble, oil-soluble and insoluble oilfield chemicals. The method was convenient, low dependence on instruments and suitable for batch processing, while the results were precise and accurate. The scheme solved the existing fluoride analysis problems of oilfield chemicals, such as poor integration, high labor intensity and low analysis efficiency, which were great significance for identification of contaminated fluoride components and environmental risk control for oilfield chemicals.
