现代装修及区域环境的破坏,使得甲醛等有机物经常与区域颗粒（粘土）在室内空气中同时存在。吸附了有害气体的颗粒物对室内人员的危害更大。本文搭建了颗粒物吸附实验台,实验研究了空气含湿量对中国东北某区域黑土颗粒表面甲醛吸附特性的影响。研究结果表明,甲醛在粘土颗粒表面的吸附与其接触时间有关,随着接触时间的延长,颗粒对甲醛的吸附量增大,但是,一定时间（12h）后其吸附量值逐渐趋于稳定。吸附饱和的特征极其明显,干燥条件下吸附饱和时单位质量颗粒物的吸附量为1.18mg/g,最大吸附速率为0.27mg/（h.g）。湿度（含湿量）能够改变对颗粒物吸附甲醛的量,含湿量越大,颗粒吸附甲醛的量越多,当含湿量为0.085kg/m3时,最大吸附值为2.67mg/g。

Building decoration and regional environment damage lead to the coexistence of formaldehyde or other organic with regional particles like Clay Particulate Matters (CPM) in indoor air. Generally the particles with harmful gases are more harmful to human. In this study the particles adsorbed system has been built up and the effect of air moisture content in air on formaldehyde adsorption on the black clay particles from the northeast of China has been studied. The experimentally results show that the adsorption of formaldehyde on the CPM is related to the contact time between the two substances, The longer the contact time, the greater the amount of formaldehyde adsorbed. However, 12 hours later, the amount of formaldehyde adsorbed change no longer. Obviously the adsorption saturation exists. In dry air condition the adsorption capacity of the CPM is 1.18 mg/g. The maximal adsorption rate is 0.27mg/(h. g). The moisture content of air can change the adsorption saturation capacity of the CPM. The greater the air moisture content, the greater the adsorption capacity. The maximal adsorption capacity, 2.67mg/g appears when the air moisture content is 0.085kg/m3 in the study.
