2024年2月15日 · PAPs are a family of phosphoric acid esters, which consist of one (monoPAPs), two (diPAPs), or three (triPAPs) polyfluoroalkyl group (−CH 2 CH 2 (CF 2) x F), where x can be 4, 6, 8, 10 and 12 [24].

2016年12月15日 · Polyfluoroalkyl phosphates (PAPs), a group of fluorotelomer alcohol (FTOH)-based surfactants commonly used in water- and grease-proof food contact paper, have been suggested as a direct source of human exposure to health …

Polyfluoroalkyl phosphate mono-, di-, and tri-esters (mono-, di-, and triPAPs) are used to water- and grease-proof food packaging materials, and these chemicals are known precursors to perfluoroalkyl carboxylic acids (PFCAs). Existing analytical methods for PAPs lack sample clean-up steps in the sam …

2024年2月15日 · Polyfluoroalkyl phosphate esters (PAPs) are emerging substitutes for legacy per- and polyfluoroalkyl substances (PFAS), which are widely applied in consumer products and closely related to people's daily lives. Increasing concern has been raised about the safety of PAPs due to their metabolism into …

2013年7月15日 · A new method using ultrasonic extraction and solid phase extraction (SPE) clean-up pretreatments was developed for the analysis of mono-, di- and tri-substituted polyfluoroalkyl phosphates (abbreviated as mono-PAPs, di-PAPs and tri-PAPs) and perfluorinated phosphonic acids (PFPAs) in sludge from wastewater treatment plants (WWTPs).

2013年7月15日 · A new method using ultrasonic extraction and solid phase extraction (SPE) clean-up pretreatments was developed for the analysis of mono-, di- and tri-substituted polyfluoroalkyl phosphates (abbreviated as mono-PAPs, di-PAPs and tri-PAPs) and perfluorinated phosphonic acids (PFPAs) in sludge from was …

Chemistry Department, 50 Stone Road East, Guelph, Ontario, Canada, N1G 2W1 Introduction Polyfluorinated phosphate esters can be mono‐, di‐, or tri‐substituted (monoPAPs, diPAPs or triPAPs respectively) and the polyfluorinated alkyl chain …

Perfluoroalkyl phosphate mono-, di-, and tri-esters, also known as mono-, di- and triPAPs, are commonly used in food packaging material due to their water and grease repellent properties.

2023年2月13日 · Both columns did not give satisfactory results for polyfluorinated phosphate monoesters (mono-PAPs) (e.g., PFHxPA, PFOPA). The addition of 1-methyl-piperidine as an ion-pairing agent to the mobile phase (41) produced high signal suppression and inefficient separation for PFAS in both columns.
