Abstract: 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 CTABas buffer solutions'pHvalues increase, the electroosmotic mobility becomeslower.At the same ionic strength, the buffer type affects the electroosmotic veloclty and themigration order for iodide and iodate.

Key words: Capillary electrophoresis, Electroosmotic flow, Iodide, Iodate
