SbSn intermetallic compound with Al addition was prepared via ball milling

when Sb and Sn powders were mixed with a small amount of Al powder.By removing Al by alkali dissolution

the specific surface area of SbSn alloy was expected to enlarge.The bulk phase structure

specific surface area and melting point were determined by XRD

BET and DSC.Its specific surface area was enlarged more than 7 times when Al addition was 5%.The results showed that expansion of specific surface area was favorable for increasing desulfurization efficiency.When surfactant addition was 0.19%

reaction time was over 18 h

voltage was assigned at 12.54 V

desulfurization efficiency reached 37.9% for emulsion of W(20)/O(80) using specific surface area of SbSn 6.43 m2·g-1 supported on wire mesh as medium.The desulfurization mechanism was explained that there was electrochemical reaction between sulfide and SbSn surface under electric current induction

in combination with physical adsorption on active sitelike vacancy caused by removing Al on alloy surface.
