This study summarizes the latest advancements in solid-phase extraction techniques for the trace-level analysis of PFCAs from water matrices. The methods have been highlighted for their ease of applications, low cost, robustness, low solvents consumption, high pre-concentration factors, better extraction efficiency, good selectivity, and recovery of the analytes. The article also demonstrates the effectiveness of some porous materials for the adsorptive removal of the PFCAs from water matrices, and discusses the mechanisms, success, and limitations of the SPE/adsorption techniques.
Perfluoroalkyl carboxylic acids (PFCAs) are sub-class of perfluoroalkyl substances commonly detected in water matrices. They are persistent in the environment, hence highly toxic to living organisms. Their occurrence at trace amount, complex nature and prone to matrix interference make their extraction and detection a challenge. This study consolidates current advancements in solid-phase extraction (SPE) techniques for the trace-level analysis of PFCAs from water matrices. The advantages of the methods in terms of ease of applications, lowcost, robustness, low solvents consumption, high pre-concentration factors, better extraction efficiency, good selectivity and recovery of the analytes have been emphasized. The article also demonstrated effectiveness of some porous materials for the adsorptive removal of the PFCAs from the water matrices. Mechanisms of the SPE/ adsorption techniques have been discussed. The success and limitations of the processes have been elucidated.
