Characteristics of PrekotAC as Formulated Filter AIDS and Its Performance to Adsorb Volatile Organic Compound

The characteristics of a formulated filter aids material known as PrekotAC which is a combination of an adsorbent, activated carbon with a pre-coating material was investigated in this study. PrekotAC, was formulated into two different weight ratios of 5:95 and 10:90 respectively. The relationship between the adsorption properties and the characteristics of the formulated materials in terms of its particle size distribution, particle density, bulk density, moisture content as well as its BET surface area was investigated. A specific amount of 100mg of formulated filter aids was placed in a fixed glass tube and subjected to a given concentration of toluene at the temperature of 25°C and 1.0 l pm gas flow rate. The adsorption properties of each filter aids material was tested under various time where the amount of toluene adsorbed by the filter aids was analysed using gas chromatography equipped with flame ionization detector (GC-FID). The ability of the formulated filter aids to adsorb toluene was presented and discussed in this paper.
