以Span-80——二-(2-乙基己基)-二硫化磷酸——煤油为膜相,稀HCl为内相,在高速搅拌下制成油包水型乳状液,按L16(4~3×2~6)正交表考察了离子载体二-(2-乙基己基)-二硫代磷酸的用量,Span-80的用量、内相酸度、外相酸度、乳状液体积和料液体积之比(Rew)、膜相体积与内相稀HCl体积之比(Roi),搅拌时间、搅拌速度、温度等九个 Span-80-di- (2-ethylhexyl) -disulfidic acid-kerosene was used as the membrane phase and dilute HCl was used as the internal phase to prepare a water-in-oil emulsion at high speed. 3 × 2 ~ 6) orthogonal table was used to investigate the effects of the amount of ionic carrier, di- (2-ethylhexyl) -dithiophosphoric acid, the amount of Span-80, the internal phase acidity, the external phase acidity, the volume of the emulsion and the volume of the liquid (Rew), volume ratio of membrane phase to inner dilute HCl volume (Roi), stirring time, stirring speed and temperature
