摘要： Method of making an ion exchange material in which a ceramic material is ion-implanted with sulfur, carbon, phosphorus, or nitrogen, which is oxidized to sulfate, carboxylate or carbonate, phosphate, or nitrate, respectively, or the nitrogen is reduced to amine or amide. Alternatively, a mixture of ceramic powder and a binder containing sulfur, carbon, phosphorus or nitrogen is heated in a non-oxidizing atmosphere to a temperature up to 1000°C. The sulfur is then oxidized to sulfate, the carbon to carboxylate or carbonate, phosphorus to phosphate, and nitrogen to nitrate, or the nitrogen is reduced to amine or amide. Also a method of treating acidic aqueous solutions containing dissolved radioactive materials by passing them through an ion exchange column containing the ion exchange material made by the afore-mentioned methods.
摘要翻译： 制造离子交换材料的方法，其中将氧化成硫酸盐，羧酸盐或碳酸盐，磷酸盐或硝酸盐或氮的硫，碳，磷或氮离子注入陶瓷材料，或将氮还原成胺 或酰胺。 或者，将陶瓷粉末和含有硫，碳，磷或氮的粘合剂的混合物在非氧化气氛中加热至高达1000℃的温度。然后将硫氧化成硫酸盐，将碳氧化成羧酸盐或碳酸盐， 磷至磷酸盐，氮至硝酸盐，或将氮还原为胺或酰胺。 也是一种通过使含有溶解的放射性物质的酸性水溶液通过含有由上述方法制成的离子交换材料的离子交换柱来处理酸性水溶液的方法。
