vacuum
uv process for pfas removal

Type of project: BSc/MSc Thesis or internship
Starting date: 1st March, 2024 or later
Duration: at least 5 months
Allowance: €200 or 400 per month, subject to the personal situation
Location: Wetsus – European centre of excellence for sustainable water technology (Leeuwarden, the Netherlands)

There are a few possibilities for allowances:
– The allowance for students is €200. The student can apply for ‘Wetsus Grant’ allowance (€200 extra; an internal committee decides if the allowance will be granted).
– Students can apply for Erasmus; (if the Erasmus grant is less than €400, the student can apply for the Wetsus Grant).
– Erasmus
*The Wetsus Grant allowance is not guaranteed and must be approved by the Grant Committee.

Project description:
Per- and polyfluoroalkyl substances (PFAS) have been widely used for industrial applications and consumer products and are frequently detected in surface water and drinking water. PFAS are bioaccumulative and toxic, which poses risks to human health and the environment. Due to the stability of the C-F bonds, PFAS are highly persistent in the environment. Hydrated electrons (eaq-), can cleave the C-F bond. Vacuum UV (VUV) at 184.9 nm photolyzes water molecules into various reactive species, including eaq-, requiring no additional chemical addition. Apart from eaq-, hydroxyl radicals (HO·) are generated to assist the oxidation of defluorinated PFAS products.

This project will focus on finding optimal experimental conditions for PFAS degradation with the presence of chloride in VUV processes using a collimated beam reactor.  

Main tasks:
-Perform PFAS degradation experiments in collimated beam reactor;
-Analyze water samples using different methods.

Requirement:
-Currently enrolled as a BSc or MSc student (non-EU citizens must be enrolled at a Dutch university to be eligible for application);
-Background in chemistry engineering, environmental science or related fields;
-Good communication in English – both written and oral;
-Motivated, responsible, and organized;
-Experience with laboratory work is preferable.
