Abstract

The possibility of replacing potentially hazardous perfluorooctanoic acid (PFOA) by nonfluorinated analogs in the technology of low-water decontamination using liquefied Freon HFC-134a was demonstrated. The efficiency of the radionuclide extraction from the fabric surface with formulations based on PFOA and on alkylbenzenesulfonic acid (ABSA) was compared. The emulsion formation in the PFOA–water–Freon and ABSA–water–Freon systems was detected; it favors the radionuclide extraction from the fabric surface. The optimum reactant concentrations in the system were determined.

全氟辛酸和烷基苯磺酸萃取液化氟利昂HFC-134a中放射性核素的比较

在液化氟利昂HFC-134a低水净化技术中，用无氟类似物取代具有潜在危险的全氟辛酸（PFOA）的可能性得到了证明。比较了PFOA和烷基苯磺酸（ABSA）两种配方对织物表面放射性核素的萃取效果。检测了pfoa - water -氟里昂体系和absa - water -氟里昂体系中乳化液的形成；它有利于从织物表面提取放射性核素。确定了体系中最佳的反应物浓度。
