COMPARATIVE STUDY OF ADSORPTION ACTIVITY OF ACTIVATED CHARCOAL AND SILICA GEL IN CASE OF WATER/TOLUENE MIXTURES

Efficiency of the liquid phase adsorption of toluene has been investigated for two common and widely used adsorbents: activated charcoal and silica gel. The adsorption values were determined using the UV-photometry method, where the solution’s absorbance has been measured at the wavelength, which co...
