Abstract  

Volatile organic compounds (VOCs) are the main factors involved in pollution control and global warming in industrialized nations. Various treatment methods involving incineration, adsorption, etc., were employed to reduce VOCs concentration. Various absorbents, such as activated carbon, zeolite, silica gel or alumina, and so on were broadly used to adsorb VOCs in various industrial applications. Differential scanning calorimetry (DSC) was handled to analyze the thermal characteristics of absorbents. Typically, a scanning electron microscope (SEM) has been used to evaluate the structure variation of absorbents under high temperature situations. In view of pollution control and loss prevention, versatility and analysis of recycled adsorbents are necessary and useful for various industrial applications.

Abstract  

Potassium tetratitanate K2Ti4O9 was synthesized from the anatase-K2CO3 starting materials by the heating calcination. DTA, TG, DTG and XRD methods were used to study the formation of intermediate compounds and the final product. The characterization of the K2Ti4O9 crystals was carried out by means of scanning electron microscope (SEM).
