Project Overview 

The aim of the project is to develop prototypes of polymer based nanoporous membrane sensors for electrochemical analysis of treated wastewater to bind and analyse heavy metal contaminants.

Project Description 

The quality of treated wastewater for agriculture is under more and more stringent control - particularly heavy metal contamination. Heavy metal contamination, such as e.g. cadmium, copper, lead and nickel, is one of the more difficult problems of water contamination to analyse. Analysis of water for heavy metal contamination is a slow and expensive process and usually requires the shipping of samples to distant labs with a minimum turn around time of 24 hours though routinely 3-5 days. The standard method for heavy metal analysis of water uses the slow, expensive and cumbersome techniques of atomic absorption spectroscopy (AAS) or inductively-coupled plasma mass spectroscopy (ICP-MS). Electrochemical water analysis, such as anodic stripping voltammetry (ASV), is attractive because it is fast, portable and inexpensive. The aim of this PhD project is to develop a cheap electrode for the analysis of treated wastewater using functionalized nanoporous membranes. The need for such a sensor is clear and the low cost and ease of use of the proposed sensor will make protecting the quality of treated waste-water cheap and easy and therefore more common and accessible to more people.

Location: 
University of Southampton, Highfield Campus
Training: 

The INSPIRE DTP programme provides comprehensive personal and professional development training alongside extensive opportunities for students to expand their multi-disciplinary outlook through interactions with a wide network of academic, research and industrial/policy partners. The student will be registered at the University of Southampton and hosted in the Chemistry Department in close collaboration with Quantum, Light and Matter Group in Physics.

I suggest add some details of the general skills training that the student will get -

Specific training will include:

  1. The preparation of functionalised nanoporous polymer membranes for binding heavy metal ions in wastewater
  2. The chemical synthesis of a variety of nanoparticles for functionalising the nanoporous membranes.
  3. The electrochemical analysis of heavy metal ions in wastewater using the nanoporous membrane sensors
  4. A vast range of techniques to characterize nanomaterials.
