| Abstract: | With triethanolamine as the absorbefacient and parafuchsin as the chromgenic agent, the spectrophotometric determination method of sulfur dioxide in the air is discussed. The standard deviation of the method is 0.001?85, the relative standard deviation (RSD) is equal to 0.3%, the minimum detection is 0.05μg/mL, and the sampling efficiency is near 100%. The result of the experiment shows that the method is satisfied with the determining request of the sulfur dioxide in the air. |
