Description
The flux of uranyl nitrate across cellulose acetate was determined using TOPO as a carrier. TOPO particles were physically entrapped in the membrane, which prepared by phase inversion method. The dominating factors were the amount of plasticizer, CTA-TOPO ratio in the membrane, uranium concentration in the feed solution, acidity and the solution temperature. And the transport phenomena of uranyl nitrate across this membrane were microscopically analysed by SEM. The increase of the membrane stability was observed when TOPO was used as a carrier. Another new technology to economically reduce the low-level liquid waste through the membrane is tested in a laboratory scale. (Author)
