Because they are biodegradable and work well in low energy separations, surfactants are an active area of interest in separations science. This book covers surfactant-based separations for the chemical and biochemical process industries and analytical chemistry. It includes discussion of widely used processes and novel techniques, such as, surfactant-enhanced ultrafiltration, ground water and soil remediation, surfactant absorption and flotation processes, extraction processes, recycling of paper and plastics using surfactant, and analytical separations using surfactants.
