چکیده انگلیسی
The emulsification solvent extraction of phosphoric acid by tri-n-butyl phosphate was investigated using a high-speed shearing machine. The effects of phase ratio, rotor speed, extraction time, extractant and phosphoric acid concentration on extraction yield and drop size were studied. The emulsification solvent extraction achieved the same extraction yield as the conventional solvent extraction ranging from 3000 to 5000 rpm and the extraction rate increased by 120 times. The extraction rate increased by increasing the oil to aqueous phase ratio. The same extraction yield could be reached at 1000 and 2000 rpm as the conventional extraction by adding kerosene. Emulsification became easier with higher phase ratio or more kerosene. Higher rotor speed, extractant concentration and lower phosphoric acid concentration contributed to smaller drop size. The phase ratio of tri-n-butyl phosphate to phosphoric acid hardly affected drop size. A model was proposed to predict average drop size to provide information for demulsification.
