Description

Perfluoroalkyl substances (PFAS) are man-made chemicals that are ubiquitous in society. PFAS offer water/oil repellence and non-stick properties, and are featured in numerous consumer products, including kitchenware, paints, upholstery and performance textiles.

Companies receiving and processing textiles have new regulations imposed by the Environment Agency, reducing PFAS limits in product formulations. Recycled carpet is one such material in societal products that is affected, which threatens to undermine the ability to recycle carpet fibres and undermine recycling businesses and their operations.

There is a growing need for rapid analytical methods for the determination of PFAS, not least because UK testing capacity is limited, slow and expensive. Fundamental research is required before rapid testing can become a commercial reality. There is a need to develop accurate and robust portable testing methods capable of providing rapid analysis for PFAS in environmental samples. This PhD will attempt to fill this gap. 

The project will work alongside the Circular Economy Chemistry research group at Manchester Metropolitan University in collaboration with an external client. The project will design an electrode formulation using screen-printed electrodes to design a rapid and portable solution to speed up PFAS analysis at point-of-release. 

Project aims and objectives

The project aims to develop a proof-of-concept portable analytical method for the detection of targeted PFAS molecules, and to demonstrate the applicability of the technology within a known PFAS transport environment.

The objectives of the research are:

  • Review PFAS affinities to materials, such as polymers, chemicals and cell membranes.
  • Design a new analytical sensing strategy for PFAS based on affinities to materials (that is using stability constant data), to incorporate as a sensing element for electrochemical detection.
  • Fabricate printed electrodes incorporating PFAS sensing elements.
  • Optimise an electrochemical PFAS detection method using the fabricated electrodes, exploring the effects of interferent molecules such as humins.
  • Map PFAS transport within client’s product life cycle using the new detection method, validating using advanced mass spectrometry techniques.

Entry Requirements

The qualifications, skills, knowledge and experience applicants should have for this project, in addition to our standard entry requirements.

The successful candidate will work within our brand new, state-of-the-art £117M Dalton Building, working within the Department of Natural Sciences, spanning the Circular Economy Chemistry Group, the Environmental Forensics Group, and the Electrochemistry Group. They will become part of our growing, active doctoral community. They will fit into the Environmental Change and Adaptation research strength.

The candidate is required to have a BSc as a minimum in a related discipline (e.g. chemistry, environmental science, engineering), and demonstrate how their study has incorporated analytical detection methods into individual or group project work.

The candidate should demonstrate the following essential criteria:

  • Experience with dynamic electrochemical methods (including cyclic voltammetry).
  • Experience using liquid chromatography and mass spectrometry (and associated analytical techniques). 
  • Ability to work in a laboratory environment independently.
  • Experience in UK laboratory safety practices. 
  • Experience in handling, extraction and analysis of PFAS.

The candidate may demonstrate the following desirable criteria:

  • Awareness of the environmental challenge and risk associated with PFAS.
  • Ideas on a detection strategy for PFAS.
  • Awareness of current PFAS regulations.
  • Evidence of good communication skills.
  • Advanced electrochemical methods (e.g. electrochemical impedance spectroscopy).

Knowledge of PFAS production and transport in the environment (e.g. through sand/fibres/waxes).
