A method for the determination of trace element Fe and As in compound fining agents for ultra-white rolled glass was developed.The samples were heated and dissolved in H2SO4 and HBr.The ICP-OES was used,using Sc as internal standard element and adding ionization inhibitor can effectively correct the signal suppression of target element caused by matrix interference and ionization interference,and the recovery rate of standard addition was 95％～105％.
