Abstract

Environmental problems have showen over the past decades due to the rapid development of the world economy and the continued growth of the population. Ocher has been widely used for water treatment research, but few studies have been conducted on adsorption of air pollutants using ocher and porous diatomite earth for indoor air purification. In this study, ocher and diatomite earth were sintered with filters to remove indoor air pollutants. The four types of TMA, H2S, NH3 and CH3COOH were used to study the adsorption efficiency of ocher and porous diatomite filters. With the proper use of ocher, diatomite and copper catalysts, indoor air pollutants could be adsorbed. Alkaline substances (TMA and NH3) and acidic substances (H2S and CH3COOH) were able to adsorb at 120 and 90 minutes, respectively.
