概要

• 論文の詳細を見る

• An inorganic ion exchanger sodium stannosilicate has been synthesized. Its composition, chemical and thermal stabilities and ion exchange properties have been studied. This material is obtained as hard granules and is very stable at high temperatures. Its ion exchange capacity for Ag<SUP>+</SUP> is 2.25 mequiv g<SUP>−1</SUP>. The material shows high selectivity towards Ag<SUP>+</SUP> which has been separated quantitatively from Pb<SUP>2+</SUP>, Hg<SUP>2+</SUP>, and Cu<SUP>2+</SUP>. Recovery of Ag<SUP>+</SUP> from dilute solutions has also been studied.
