摘　　要：对沸石吸附甲醛进行了试验研究,探讨了用氢氧化钠、盐酸及有机改性的沸石对吸附甲醛的影响。结果表明,有机改性的沸石对甲醛的吸附要比天然沸石和无机改性沸石对甲醛的吸附效果明显。Absorption of formaldehyde by zeolite was studied, and the effect of the modified natural zeolite by sodium hydroxide, hydrochloric acid and organic compound adsorption was discussed. The results show that absorption level of formaldehyde by organic - modified zeolite is higher than that by natural zeolite and inorganic - modified zeolite.
