[Background]Extraction of carbon from water is a crucial preprocessing step for measuring 14C in environmental waters using liquid scintillation spectrometry.[Purpose]This study aims to explore the optimal technological conditions for extracting carbon from water using wet oxidation method.[Methods]A wet oxidation system combining sodium persulfate and Fenton's reagent,along with phosphoric acid acidification and nitrogen bubbling,were employed for the wet oxidation carbon extraction experiments on two types of water samples with known(deionize...
