摘　　要：建立了离子色谱法测定蟹肉中亚硫酸盐（二氧化硫）的检测方法，回收率在73．1％～92．6％和精密度〈6．7％，探讨了样品前处理方法及色谱条件；通过比较离子色谱法与国标法，结果表明，两方法之间没有显著性差异，离子色谱法克服了国标法中汞的污染和色素干扰问题。The method for determination of sulfite in crab by ion chromatography was established, the sample recoveries was in the range of 73.1% to 92.6% and the relative standar deviations （RSD）〈6.7%. Investigated the conditions of Pre- treatment method and chromatographic;There was no significant difference between the national standard method and the IC method, And the IC method no pollution and no pigment interference problem of mercury.
