摘　　要：空气致敏花粉是空气污染的一个重要来源,为研究磁性材料对花粉的吸附性能,寻找低成本、高效率、绿色环保的花粉吸附材料,进行花粉采集,设计实验,探究了不同材料对运动的干花粉和活性花粉的吸附性能。实验结果表明,干花粉经过传动装置落到圆台上,花粉数目分布不具有偏向性;活性花粉经过传动装置落到圆台上,向磁性材料位置聚集。与静电吸附载玻片、粘附剂、纱布相比较,磁铁与铁基氧化物组合吸附材料对运动的活性花粉的吸附数目最多,可能是活性花粉在运动过程中带了电,磁性材料对带电粒子具有约束性所致,但其具体吸附原理还需后续探究得出。该实验证明利用磁约束对活性花粉进行收集是可行有效的,从而为制备绿色环保的磁性吸附材料收集致敏花粉提供依据。Air-sensitized pollen is an important source of air pollution.In order to study the adsorption properties of magnetic materials on pollen and find low-cost,high-efficiency and environmentally friendly adsorption materials,this study designs experiments to collect pollen to explore the adsorption properties of different materials on moving active and inactive pollen.The results of the experimental data show that the dry pollen passes through the transmission device and falls on the round table,and the distribution of number is not biased.The active pollen falls on the round table through the transmission device and then gathers at the position of the magnetic materials.Compared with the electrostatic slide,adhesives and gauze,the combined adsorption material of magnet and iron-based oxide adsorbs the most active pollen in motion.The possible reason is that the active pollen is charged during the movement,and then be bound to the magnetic material.This experiment proves that the use of magnetic confinement to collect active pollen is feasible and effective,thereby providing a basis for preparing green and environmentally friendly magnetic adsorption materials to collect allergic pollen.
