The surface tension of the mixed aqueous solution of sodium perfluorooctanoatetrimethylamine(or triethylamine) hydrochloride has been determined.

Perfluorinated carboxylic acids(PFCAs) especially perfluorooctanoic acid(PFOA) are a new type of persistent and bioaccumulative organic pollutants,and they have been widely detected in various environmental media.

As a kind of emerging persistent organic pollutant(POPs),perfluorooctanoic acid(PFOA)and its salts have caused global ecosystem pollution,and become a new research topic of POPs.

Trend on the PFOA in fluorinated applications;

A new method was developed for the determination of perfluorooctanesulfonate(PFOS) and perfluorooctanic acid(PFOA) in sewage sludge samples.

With the EU-wide restrictions on perfluorooctane sulfonates (PFOS) used in applications, the potential human health concerns on PFOA had been attained increasing focus.

A novel methylacryloyloxyl-ethyl perfluorooctanoate(MAEF) monomer was prepared via a two-step reaction with perfluorooctanoic acid as a starting material.

The complexes of perfluorooctanoic acid (PFOA) and polystyrene-b-poly-(4-vinylpyridine) (PS-b-P4VP) can induce micellization of the block copolymer in their common solvent chloroform.

Perfluorooctanoyl chloride(I) was prepared by reaction of perfluorooctanoic acid and SOCl 2 at 85 ℃ for 1 h,then Ⅰ was treated with ethanolamine at 30 ℃ for 3 h to give N hydroxyethyl perfluorooctanamide(Ⅱ).

Disposing of ammonium perfluorooctanoate(APFO) waste water from the production of fluorine polymers and recovering APFO from the sediment obtained through waste water treatment were researched in the thesis.

At first, the best synthetic conditions have been achieved by orthogonal experiment according to one step reaction of perfluoro caprylic acid and a kind of aminofunctional siloxane.
