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.

the pictures of EG/paraffin/OMMT.
The microstructures of EG/paraffin, OMMT/paraffin, and EG/paraffin/OMMT are observed by a scanningelectronmicroscope (SEM) (Hitachi E1010). The melt point and
morphology was analysed by Hitachi S-4300 scanningelectronmicroscope (SEM) and transmission electron microscope (TEM). Also, selenium concentration was measured by flame emission atomic absorption spectrometer (Thermo ICE 3000) and atomic fluorescence
radiation. Sample scanning was done between the angles of 20–80°. Diffraction peaks were analyzed and indexed according to the diffracting planes of different phases. The morphology of samples was examined using a scanningelectronmicroscope (SEM, Hitachi S

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).
