The transport behaviour of yttrium from nitrate medium was investigated using dinonyl phenyl phosphoric acid (DNPPA) as a carrier in liquid membrane phase, employing microporous hydrophobic hollow fibre supported liquid membrane (HFSLM) module. The influence of feed composition, carrier concentration, feed acidity, strip acid concentration and flow rate of feed on permeability and flux of Y(III) is discussed. The stripping solution was sulphuric acid solution. Increasing the carrier concentration increased the % transport of yttrium, while an increase in the feed metal concentration decreased the percentage transport.A lower acidity in the feed solution and 3 M H₂SO₄ concentration in the stripping phase are favourable for the transport process due to the increase of mass transfer driving forces. The % transport of yttrium increased with an increase in flow rates up to 100 mL/min. Under optimized conditions of 0.2MDNPPA, 1g/LY(III), 0.05M feed acidity, 3Mstrip acid (H₂SO₄) and 100mL/min flow rate, the % transport of yttrium was more than 95% in 5 h of operation.
