摘要
硅藻土具有超强的吸附性能,能吸附室内甲醛等有害气体,但其只吸附不分解,易产生室内二次污染。以硅藻土为主要原材料,对室温下纯硅藻土和负载二氧化锰硅藻土的除甲醛性能进行了研究。研究结果表明:纯硅藻土在初期甲醛吸附量快速上升,一定时间后甲醛吸附量趋于平缓;随着二氧化锰与硅藻土的质量比的提高,负载二氧化锰硅藻土的甲醛吸附量逐渐升高,达到最大值后缓慢下降。
Diatomite has superior adsorption properties,it can absorb indoor formaldehyde and other harmful gases.But the formaldehyde can be adsorbed instead of decomposed,which easily leads to indoor secondary pollution.With diatomite as the main raw material,the formaldehyde removal performance of pure diatomite and diatomite-loaded manganese dioxide at room temperature were studied.The research results showed that the adsorption amount of formaldehyde in pure diatomite increased rapidly at the initial stage and tended to be gentle after a certain time.To diatomite-loaded manganese dioxide,the formaldehyde absorption gradually increased with the increase of the mass ratio of MnO2 to diatomite,after reaching the maximum value,then decreased slowly.
