Box 1346 Ann Arbor, Ml 48106- 1346 (ii) ABSTRACT (iii) The swelling of a sulphonic acid resin in the Li(l), K(l), Ag(l), Cu(ll), Ni(ll), Mn(ll), Co(ll\ Cr(lll), and Fe(lll) forms, in aqueous ammonia solution, has been described in this thesis. The swelling of some metal form resins in aqueous ethylenediamine and propylenediamine solutions has been studied for comparison. It was found that the alkali metal form resins did not show any preference for ammonia but other transition metal form resins did show such preference for ammonia and for the other bases studied. The absorption of base by such resins was quantitative and hence it v/as possible to construct the formation curves for the ammine and amine complexes and to derive stability con stants by Bjerrum!s half-step method, for the amine complexes formed in the resins. -

Assessment of End-Of-Life Opportunities for Reverse Osmosis
Assessment of End-of-Life Opportunities for Reverse Osmosis Membranes Will Lawler A thesis in fulfilment of the requirements for the degree of Doctor of Philosophy School of Chemical Engineering Faculty of Engineering March 2015 i. Abstract Reverse osmosis (RO) membranes are now core to modern desalination processes and are widely used around the world. Based on the increasing number of desalination plants, and the finite lifespan of the membranes, the resulting number of used RO modules to be discarded is becoming a critical challenge. The overall aim of this study is to identify, develop and assess alternative end-of-life options for used RO elements and investigate the associated technical readiness, environmental impact, financial considerations and legislative challenges. The assessed end-of-life alternatives include, direct reuse of the old membranes within lower throughput systems; chemical conversion into porous, ultrafiltration (UF) like filters; direct reuse or recycling of the various module components; various energy recovery techniques, and landfill disposal. The results show that direct reuse is a promising application that can be utilised with minimal additional treatment or infrastructure; however, module storage techniques are a critical consideration, particularly as membrane drying has a significant and irreversible impact on membrane performance due to pore collapse in the polysulfone support layer. The method for chemical conversion with controlled exposure to NaOCl has been optimised, resulting in promising organic and virus removal properties, comparable to commercially available 10 – 30 kDa molecular weight cut off UF membranes; however, there was significant variation in hydraulic performance, ranging from 8 – 400 L.m-2.h-1.bar-1. -

Box 1346 Ann Arbor, Ml 48106- 1346 This thesis is dedicated to the select band o f people, including the most recent arrivals and the sorely missed departed, that I hold closest in my affections. "At the end of the day" they make It all worthwhile. Remember, in the words of the famous actor whose name at present escapes me; "Nobody said it would be easy". Although my own feeling is that Nobody was probably wrong. II Thesis abstract The convulsant alkaloid strychnine is a selective and highly potent antagonist at postsynaptic receptor for the inhibitory neurotransmitter glycine . These properties have led to the extensive use of strychnine as a ligand to probe the postsynaptic glycine receptor. Despite the recent increased understanding of the molecular structure of this receptor protein there is still much dispute as to the nature of the interaction between glycine and strychnine. -
