Studies on Carrier-Free Silver-111 with Membrane Filters

막여과지에 의한 무단체 Ag-111에 관한 연구
Won Mok Jae

무단체 Ag-111의 상태를 여과법에 의하여 연구하였다. 이 연구는 막여과자에 의하여 수용액에 있어서 Ag-111의 pH 및 농도변화에 대한 효과를 조사하였다. 이 연구결과 막여과지에 대한 Ag-111의 부착은 Freundlich 흡착 등온식에 따르고 Ag-111의 흡착상태는 AgOH 형태로 존재하며 높은 pH에서 흡착성이 없는 Ag(OH)2-는 Ag의 흡착을 방해하는 것으로 생각된다. 또한 무단체 Ag-111는 수용액중에서 Ag+상태로 존재하고 있다.

The state of carrier-free silver-111 has been studied by applying filtration method. The studies involved that the effects of pH and concentration of silver-111 in aqueous solution have been determined with membrane filters. The present studies revealed that the retainment of silver-111 on membrane filters followed Freundlish adsorption isotherm, and the adsorbed state of silver-111 was present in the form of AgOH. Also it was supposed that the formation of the non-adsorbed hydroxide of Ag(OH)2- may prohibit the existance of AgOH at higher pH, and it seems to be valid that the carrier-free silver-111 in aqueous solution exists in Ag+ state.
