Abstract：

The mass transfer behavior of ammonia-nitrogen from aqueous media through hollow fiber supported liquid membrane process consisting of di(2-ethylhexly)phosphoric acid（D2EHPA） in kerosene, supported on the polypropylene hollow fiber membrane, was studied. The influence of the initial pH value and ammonia-nitrogen concentration in feed phase, the carrier concentration and the acid concentration in stripping phase on ammonia removal is also characterized by the removal rate. The primary reason of the ammonia removal rate which is constantly declining is discussed by the contrast experiment. The results show that when the acid concentration is 2 mol/L and the pH value is within the range of 8 to 13, the removal rate can be improved by increasing ammonia concentration, pH value of feed and the carrier concentration. The capacity of D2EHPA-kerosene-H2SO4 system for ammonia mass transfer decreases with decreasing ammonia concentration.The decline of Ammonia removal rate is mainly caused by lowering pH and reducing ammonia concentration in feed solution.Adjusting the pH value can improve the control and effects of mass transfer.
