Opis ogólny

Perfluorobutyric acid is an effective additive for zinc electrodeposition.

Zastosowanie

Perfluorobutyric acid was used as mobile phase modifier for enhancement of selectivity in the HPLC analysis of histone proteins. It was used as ion pairing reagent in preparative and analytical reserved phase HPLC of underivatised peptides.

Perfluorooctanoic acid (PFOA) was efficiently decomposed at Ti/SnO2-Sb anode via peroxymonosulfate (PMS) activation. PFOA degradation followed both pseudo-zero-order (0-30 min) and pseudo-first-order (30-120 min) kinetics. The pseudo-first-order kinetics constant could increase to 0.0484 min-1 (3.84 times higher than that without PMS) during...
