Abstract

This thesis describes the work undertaken between two interlinked fields of chemical research; the synthesis of novel sustainable inverse vulcanised sulfur polymers and their applications for the remediation of heavy metals. Chapter 1 includes an introduction to sulfur and its chemistry, inverse vulcanisation and its processes and a discussion of previously reported work in the field. The potential applications for inverse vulcanised sulfur polymers and background information relating to heavy metals, their toxicity and environmental contamination are also contained in this chapter. Research into new crosslinkers and the route to establishing an adaptable synthetic method suitable for the inverse vulcanisation of multiple different sustainable crosslinking agents is presented in Chapters 2 and 3. These chapters cover early initial reactions, background information on potential new crosslinkers and the synthesis and analysis of nine new polymeric materials. Chapter 4 discusses the potential application for these polymers as sorbents for heavy metal remediation. This chapter discusses routes to enhancing the surface area of these novel polymeric materials, followed by the results from in situ testing of these materials against a range of inorganic and organometallic heavy metal compounds. Detailed experimental methods and heavy metal testing protocols, information relating to the instrumentation used to generate the data presented in this thesis and the relevant analytical theory behind these techniques, is to be found in Chapter 5. Chapter 6 covers the main conclusions drawn from this research and suggests how this project could be continued in the future.
