摘要
家庭装修会造成室内环境污染,主要污染物是甲醛、苯等有机物,这些物质会对人体健康造成危害。本课题拟采用活性炭作吸附剂净化室内空气,寻求一种科学方法提高活性炭的吸附性能,以使净化过程更经济,操作简单,有利于推广使用。实验以甲醛为目标物质进行模拟研究,对比了粉末活性炭、颗粒活性炭、竹炭对甲醛的吸附效果,研究了改性活性炭对甲醛的吸附性能。通过对活性炭进行改性处理,大大提高了活性炭的吸附性能,能够有效地吸附甲醛,且吸附性能都超过了市场上吸附性能良好的竹炭。
Home decoration can cause indoor pollution, the main pollutants are formaldehyde, benzene and other organic matter, these substances are harmful to human health. The author of the subject plans to adopt the activated carbon as adsorbent to clean the indoor air, to find a scientific method to improve the adsorption properties of activated carbon to make the cleaning process more economical, simple operated and be apt to promoting. The experiments do the simulation by using formaldehyde as target substances, comparing the charcoal adsorption of formaldehyde of the powdered activated carbon and granular activated carbon and the charcoal, studying the adsorption of formaldehyde of the modified activated carbon. The modification of activated carbon can peatly improve the adsorption properties of activated carbon and effectively adsorb formaldehyde, and the adsorption properties are better than the good charcoal on the market.
