摘要
制备钠型、钙型、铁型改性粉煤灰,测试了改性粉煤灰种类及吸附次数对甲醛和氨吸附量的影响.结果表明,这3种改性粉煤灰对甲醛和氨均有一定的吸附,其中钠型改性粉煤灰对甲醛和氨的吸附量最高,与市场上销售的活性炭吸附剂相媲美,且钠型改性粉煤灰的制备成本相对较低.这将为净化室内空气方面提供一种经济、有效的新的吸附剂.
The Na-fly ash, Ca-fly ash and Fe-fly ash were prepared for the absorption test of formaldehyde and ammonia. We discussed the effect of different kinds of activated fly ash and the absorption times. According to the results, all these three kinds of fly ashes can absorb formaldehyde and ammonia, and among them, the best absorption result was given by using the Na-aetivated fly ash which was as effective as the activated carbon sorbent selling on the market. Due to the lower preparation cost, these new type of sorbents will provide us an economic and effective way for the indoor air cleaning.
