【摘要】 为探索竹炭在文物保存环境领域的应用特征,研究了不同粒径竹炭对于SO₂净化的影响并测定了竹炭的吸附量,研究了竹炭净化二元混合污染物耦合的效果。结果表明:相比果壳、柳壳、椰壳3种生物质炭,竹炭净化SO₂的效果最佳,当粒径小于1.7mm时,净化效率达到（99.6±0.2）%;单位质量的竹炭对SO₂的吸附容量为8.46mg/g;此外,低浓度NO和NO₂对SO₂没有抑制作用,但高浓度NO_x对SO₂净化有较大的抑制作用,当NO浓度为536μg/m³时SO₂的净化效果较NO浓度为268μg/m³时降低了2.9%;当NO₂的浓度从411μg/m³上升至821μg/m³时,SO₂的净化效果降低了5.7%,而SO₂对于甲酸、乙酸的净化效果抑制作用在-1%以内,且在实验浓度范围内的SO₂受甲酸、乙酸影响较低,平均净化效率分别为90.4%和90.5%。更多还原

【Abstract】 In this paper,the influence of particle size on SO₂ adsorption by bamboo carbon（BC） was studied and its adsorption capacity was determined.The ability of BC to adsorb mixed binary pollutants was also studied.The results show that BC has better capacity for SO₂ adsorption,compared with three other biomass-based activated carbons.The adsorption efficiency reached 99.6 ±0.2%when BC particle size was smaller than 1.7 mm.The unit SO₂ adsorption capacity of BC reached 8.46 mg/g of BC.No inhibition of SO₂ adsorption was found when NO and NO₂ concentration were low higher concentration NO_x were found to inhibit SO₂ purification.The purification efficiency of SO₂ reduced 2.9%when NO concentration increased from 268 |xg/m to 536 |xg/m.While it decreased 5.7%when NO₂ concentration increased from 411 μg/m³ to 821 μg/m³.The inhibition of formic acid, acetic acid purification by SO₂ ranged within 1%.Within the range of experimental concentrations,lower inhibition of SO₂ purification by formic acid and acetic acid was found,and the average SO₂ purification efficiency were 90.4%and 90.5%,respectively.更多还原
