use oxygen cylinder combustion ion chromatograph determination tablet to text the ammonia chlorine horizontal abstract goal: use The oxygen cylinder combustion ion chromatograph determination ammonia chlorine horizontal sulfur, then obtains the ammonia chlorine horizontal content according to the chemical formula. Method: Then oxidizes with the oxygen cylinder the ammonia chlorine horizontal sulfur to be the oxide compound, with includes the hydrogen peroxide peroxide solution to absorb to be the sulfate radical, the ion chromatograph determination. Finally: The returns-ratio is between 98%-102%, the linearity range is 0.02 -60ug/ml, the examination lower limitation is 0.00324ug/ml. Conclusion: Compares with other methods,it express more simply, fast, accurate, reliable. Key word: Oxygen cylinder combustion, ion chromatograph, ammonia chlorine horizontal, sulfur
