摘　　要：Some factors effected on heterogeneous hydrothermal stripping from iron-loaded organic phase of naphthenic acid-isooctyl alcohol-kerosene,such as the concentrations of initial iron and naphthenic acid,the weight of"seed"of Fe2O3,temperature and time,were investigated.The process rate equation and the relation between stripping percent and time needed were established.The results showed the proces activation energy was 114 kJ·mol-1 and the heterogeneous hydrothermal stripping was controlled by the hydrolysis of naphthenic compound of iron.Some factors effected on heterogeneous hydrothermal stripping from iron-loaded organic phase of naphthenic acid-isooctyl alcohol-kerosene,such as the concentrations of initial iron and naphthenic acid,the weight of'seed'of Fe_2O_3,temperature and time,were investigated.The process rate equation and the relation between stripping percent and time needed were established.The results showed the proces activation energy was 114 kJ·mol^(-1) and the heterogeneous hydrothermal stripping was controlled by the hydrolysis of naphthenic compound of iron.
