英文摘要
A rapid and cheap analytical method for organic fluorinated compounds (OFCs) was investigated to measure the whole amount of organic fluoride in water. The method consisted of OFCs decomposition by UV radiation with oxidant and acid addition, distillation for fluorine ion recovery, and colorimetric quantification of fluorine ion. By many experiments, anoptimal condition, about ten minutes UV radiation with suitable potassium persulfate and sulfuric acid addition, was identified to provide 60 - 100 % decomposition of perfluorinated short-chain alkyl acids. This also suggested applicability of this method in factories that deal high concentration OFCs water.
