Various separation membranes have been developed since their discovery over half a century ago, providing numerous benefits and fulfilling many applications in our everyday lives. They lend themselves to techniques ranging from microfiltration and gas separation, to what can be considered as the most advanced technique - ion exchange. This book, aimed at academic researchers, engineers and industrialists, contains a brief history of ion exchange and goes on to explain the preparation, characterization, modification and applications of these important membranes. Discussions include the use of ion exchange in analytical and medical techniques, as well as the development of future applications.

"The foundry was working at full pressure. In spite of the dismal conditions - the stifling heat, the silica dust that hung in clouds in the air, the crude ventilation, and the strenuous labour - the men seemed happy and companionable. A certain measure of security had come at last after the long years of unemployment; the dread of the dole was behind them".Life in the foundry is changing Ieuan Morgan, whose hands, once familiar only with the feel of books are now dark, knotted and fiercely strong. He dreams of writing and the day his young love Sally will come home from the convalescence home. When that day arrives Ieuan's life starts to feel complete and marriage only deepens that conviction. But much longed for success with hiswriting brings with it new temptations, when Stella Courtland, the sophisticated editor of a fashionable magazine enters the young man's life.Ride the White Stallion is the sequel to Farewell Innocence, charting the trials and travails of Ieuan Morgan at the foundry and in his family life. It is an account of a young man's creative awakening amid the challenges of domestic penury and downright hard graft. A portrait of an industrial town as well as a convincing character study, Ride the White Stallion is shot through with truth and honesty, twin hallmarks of Glynne-Jones's work.

"A world of green: a new and weird world of grim, dark shadows and frenzied activity; of conflicting sounds varying from the roar and thunder of overhead gantries, the sharp, shrill staccato beat of automatic hammers, to the echoing ring of steel upon steel, and the hollow wheezing and thumping of the hydraulic moulding machines".Starting as an apprentice at Bevan's foundry, Ieuan Morgan enters a new and testing world. His colleagues soon turn out to be his tormentors while life at home is not without its challenges. It is hard for the young man to sustain his dreams of one day being a writer, and of a better world. Things have to get worse before getting better so unemployment casts its long shadow over the town. But the lay-offs give the gifted Ieuan time to read and think and on a visit to the fair to meet Sally, a gentle, consumptiveyoung woman from the wrong side of the tracks.With this, his destiny changes course. Written with a deep authenticity born from bitter experience, William Glynne-Jones depicts life in the fictional town of Abermor and especially the daily grind of foundry life, in a workplace fraught with dangers. Farewell Innocence is a heartfelt and affecting account of a young man's rites of passage in hard times.
