【摘要】 本文对重铬酸钾法测定空气耗氧量(AOD)的实验条件进行探讨。经方法改进和现场AOD测定,结果表明,该法操作简便、快速,结果准确,重复性较好。AOD水平髓各场所空气污染程度不同而变化,能较理想的反映空气污染状况,可以作为评价室内空气污染的综合指标之一。更多还原

【Abstract】 The article inquires the utilization of potassium dichromatc method to measure AOD in the experimental conditions . The results testified that the method is simple and quick. With some changes in the method the results abtaincd is rcpcatiabc and ideally reflects the conditions of air pollution. The result may be used as one of the synthetical indexes in evalution indoor air pollution.更多还原
