稀土激活无机净化材料的空气净化性能研究

Purifying air property of inorganic materials activated by rare earth elements

简述空气净化材料的分类和特性，有害气体的特性；提出净化剂寿命的简易测试和评价方法。研究结果表明：稀土激活无机净化材料对氨气的净化效果比活性炭及合成沸石好，对二甲苯等有机中性气体的净化效果较差，而用稀土处理的活性炭材料对二甲苯等有机中性气体的净化效果显著。

Classification and feathers of materials for purifying air were introduced in brief, so did the feathers of hannful gasses. Then a practical and easy method was suggested to test and evaluate lifehme of the addihves for air cleaning. Results show that the purifying NH3 property of inorghoc materials achvated by rare earth elements is much more better than that of rare earth activated carbon and synthesized zeolites; And none of these materials can purify xylene and other neutral organic gasses; The carbon activated by rare earth elements,however, can obviously purify the neutral organic gasses.
