A review on superior advanced oxidations and photocatalytic degradation techniques for perfluorooctanoic acid (PFOA) elimination from wastewater.

Environmental Research, 2023
Perfluorooctanoic acid (PFOA) has been identified as the most toxic specie of the family of perfluorinated carboxylic acids (PFCAs). It has been widely distributed and frequently detected in environmental wastewater.

Bioaccumulation and toxicity of perfluorooctanoic acid and perfluorooctane sulfonate in marine algae Chlorella sp.

Science of the Total Environment, 2023
The ocean is an important sink for perfluorinated alkyl acids (PFAAs), but the toxic mechanisms of PFAAs to marine organisms have not been clearly studied. In this study, the growth rate, photosynthetic activity, oxidative stress and bioaccumulation were

Potential enzyme toxicity of perfluorooctanoic acid

Amino Acids, 2008
Using equilibrium dialysis, isothermal titration calorimetry (ITC) and circular dichroism (CD), the interactions of perfluorooctanoic acid (PFOA) and lysozyme were investigated under normal human physiological conditions, i.e., at pH 4.40, 6.00 and 7.40 at 37 degrees C in 0.15 M electrolyte.

Titanium oxide improves boron nitride photocatalytic degradation of perfluorooctanoic acid

Chemical Engineering Journal, 2022
2 ) creates a BN/TiO 2 composite that is more photocatalytically active than BN or TiO 2 under UV-A for perfluorooctanoic acid (PFOA). Under UV-A, BN/ TiO 2 degraded PFOA ~ 15 × faster than TiO 2 , while BN was inactive.
