The Generation Mechanism of Radical in the Silver-ion-fluted Aqueous Solution from A-type Zeolite Supporting Silver tons and Its Applications
은 이온교환 A 형 제오라이트에 의한 라디칼 발생메카니츰과 그 응용에 관한 연구
Abstract
We confirm that when A-type zeolite supporting silver lone is placed in ion-exchanged distilled water, silver ions is eluted and eluted silver ions generates hydroxyl-radical (.OH) and hydro-radical (.H) continuously, the amount of those is proportion to the silver-ion concentration. Hydroxyl-radical is not generated by super-oxide anion-radical (.O2) but by directly dissolved water. To know such a above discussed mechanism, we prepare A-type zeolite supporting silver ions, and measure the amount of the eluted silver tons by atomic absorption spectroscopy and the generated radical by ESR The radical generated by A-type zeolite supporting silver ions is discussed in the application of elecrical and electronic materials.
