摘　　要：Manipulation of electroosmotic flow in capillary electrophoresis is an importantstep for separation of inorganic anions.The type and concentratlon of electroosmotic flowmodifier (OFM) exert a tremendous influence on the electroosmotic mobllity. ln the pres-ence of CTAB as buffer solutions’ pH values increase, the electroosmotic mobility becomeslower. At the same ionic strength, the buffer type affects the electroosmotic veloclty and themigration order for iodide and iodate.Manipulation of electroosmotic flow in capillary electrophoresis is an importantstep for separation of inorganic anions.The type and concentratlon of electroosmotic flowmodifier (OFM) exert a tremendous influence on the electroosmotic mobllity. ln the pres-ence of CTAB as buffer solutions' pH values increase, the electroosmotic mobility becomeslower.
