Abstract：In view of the environmental pollution and the harm on human health of trace arsenic during com-bustion, arsenic removal from simulated flue gas was studied in a self-designed bubbling reactor with KMnO4 solution as the absorbents. The influence of KMnO4 concentration,initial solution pH value,reaction tempera-ture,SO2 concentration,NO concentration,O2 content and CO2 content on the removal of arsenic were investiga-ted respectively. The results show that the arsenic removal by using KMnO4 solution is available. The efficiency of arsenic removal could reach by 82 . 4% under the optimal conditions in which the initial concentration of ar-senic was 427 μg/m3 ,KMnO4 solution was 10 mmol/L,pH value was 5 and the reaction temperature was 50℃.
