摘要: Abstract The feasibility of using liquid-liquid sandwich-transfer extraction methods as fast analytical tools was examined. effect surfactant, acid and base concentrations on the stability sandwich membrane tested. possibility this method in pre-concentration processes investigated for chromium(VI). rate transfer radioactive 51 Cr from aqueous sulphuric to sodium hydroxide solution found be rapid at reasonable (1%) reagent tri-n-octylamine.
