Abstract: An analytical method using oxygen bomb combustion-ion chromatography for the determination of sulfur in solid biomass fuels is established.With sodium carbonate,sodium bicarbonate and hydrogen peroxide as absorption solution,the sulfides in sample is converted into sulfate ion after combustion in the oxygen bomb,and total sulfur content in the solid biomass fuels is well isolated and determined by ion chromatography.The detection limit of sulfate ion is 2.4 mg·kg-1 and the calibration graph is linear within 1.0-100.0 mg·L-1.Precision and accuracy tests show that the relative standard deviation is less than 5%.The recovery rates are between 95.56% and 99.89%,and the relative standard deviation is 1.33%.The detection result by this method agrees with that by Eschka method.The method is simple,rapid,good repeatable and suitable for the determination of total sulfur content in solid biomass fuels.
