Relevant literature also reported that activated alumina carrier should have sufficiently large pore volume and reasonable pore size distribution. After being dried at room temperature for 12h, the samples were dried in the drying oven at 110 ��. The formaldehyde adsorption property and capacity of the samples were tested in different time (6, 24, 36, 48, 60 and 72h) and calculated with mass difference subtraction, respectively. AlCl3, NH3��H2O, HNO3 and activated carbon were used as raw materials Presently, researches on the formaldehyde adsorption mainly focus on the activated carbon base materials; activated alumina studiers mainly focus on the catalyst carrier and water treatment, and there are few literatures on air purification. 2.1 Preparation of the precursor of aluminum hydroxide, AlCl3 was used as the aluminum source; NH3. Owing to the molecular size, about 3 ?, of formaldehyde, these small molecules were mainly adsorbed through micropore adsorption, and the micropore had large specific surface area with better adsorption effect. In addition, during the preparation process, some added HNO3 reacted with Al(OH)3 to generate Al(NO3)3 (3HNO3+Al(OH)3=Al(NO3)3+3H2O). Activated alumina can be used as a point-of-entry or point-of-use water treatment device. Activated alumina is a porous, solid form of aluminum oxide, otherwise known as Al 2 O 3 or alumina. There are three main forms such as Granular Activated Carbon, Powder Activated Carbon, Extruded Activated Carbon. When the calcination temperature was 450��, the remaining crystal water in pseudo boehmite was completely lost and ��-Al2O3 under transition form was generated with obvious diffraction peaks at 46�� and 66.8��; when the heat treatment temperature rose to 650��, characteristic diffraction peak of ��-Al2O3 strengthened continuously. At the same time, there was slight offsetting, indicating that the ��-Al2O3 content increased, and crystallographic form turned much better. The terms activated carbon, and activated charcoal are confusing. INTRODUCTION Activated alumina is an important adsorbent, but quite different in physical structure and chemical characteristics to activated carbon. The activated rice husk carbon was prepared thermally in two sizes 0.3 and Fig.4 depicts the N2 adsorption-desorption isotherms of the sample at 450�� heat temperature. According to the results of Table 3, the optimal condition for adsorption of carbon dioxide for all three adsorbents (activated alumina and modified activated alumina with NaOH and KOH) are under operating conditions of 20 °C and 6 bar, which in this case, the CO 2 adsorption capacity is the highest for 30NaOH-AA, 146.70 mg/g, and then 130.84 mg/g for 30KOH-AA, respectively. The reason can be explained from the prospective of Al(OH)3 phase transition and ablation samples. As one kind of porous inorganic solid materials with large specific surface area, activated alumina is one kind of fine adsorbent, catalyst and catalyst carrier. Fig.6 clearly showed that the formaldehyde adsorption capacity of the sample was excellent, and it was superior to that of pure activated carbon or activated alumina. When the heat treatment temperature was 750��, the diffraction peak of ��-Al2O3 weakened or basically disappeared, and obvious ��-Al2O3 characteristic peaks appeared at 25.9, 35.2, 37.8, 43.4 and 57.5��, so ��-Al2O3 with fairly complete crystal was mainly produced at 750��. The process was as follows. Through calculation, the formaldehyde adsorption amount of the sample was greatly larger than the sum value of activated alumina and activated carbon. Activated alumina is commonly used as a desiccant to adsorb water molecules in the air or gases to keep things dry and reduce the humidity level.. As a cost-effective desiccant, it can be found on compressed air dryers to adsorb water molecules under harsh conditions.
