ground waterfrom Hanford site, and fundamental studies of 2Nasup +}yields}Srsup2+} exchange equilibria revealed that a synthetic clay is extremely selective for sup 90}Sr with a high capacity for uptake. Comparative studies with existing Sr selectiveion exchangers clearly revealed that the present synthetic clay exhibited the best performance for sup 90}Sr removalfrom actual ground water collected

show remarkable reactivity to the brominating reagent and brominated in 92–98% yield with high purity (>99%) in a very short reaction time. Organic solvent-free conditions, a feature of the green chemistry, were successively used not only for the reactions but also for the isolation of products at the end of the reaction. The recycling of HBr by its neutralization, thereby generating additional amounts
