“…η; has been found to be inversely proportional to the solubility σ; (Yonge and Keinath, 1985). This is compatible with previous works (Martin and Al-Bahrani, 1979;Weber and Van Vliet, 1978;El-Dib and Badawy, 1979) as the solubility was found to vary inversely with adsorbability. Therefore TU was correlated with solubility.…”

“…We make note that similar monolayer capacities were determined for PAHs on activated carbon: 2.70 × 10 14 , 1.98 × 10 14 , and 1.81 × 10 14 molecule cm -2 for naphthalene, acenaphthylene, and fluorene, respectively, by Walters and Luthy (33), and 1.30 × 10 14 , 1.51 × 10 14 , 1.40 × 10 14 , and 1.24 × 10 14 molecule cm -2 for o-cresol, nitrobenzene, o-methoxyphenol, and quinaldine, respectively, on activated carbon by Martin and Al-Bahrani (34). For sorption of phenanthrene to combusted lake sediments, Cornelissen and Gustafsson (35) obtained a saturated surface coverage ranging from 2.0 × 10 13 to 1.0 × 10 14 molecule cm -2 .…”

The adsorption isotherms of a series of aromatic hydrocarbons on n-hexane soot were measured as a function of temperature and partial pressure in a coated-wall flow tube coupled to an electron-impact mass spectrometer. The specific surface area was determined for each of the samples by measuring the BET isotherm of Kr at 77 K. The gas-to-surface uptakes were fully reversible with the extent of adsorption increasing with decreasing temperature and increasing partial pressures. At low partial pressures, the isotherms were well modeled by the Langmuir isotherm for all experimental conditions, and the adsorption was found to saturate at one monolayer of coverage at approximately 2 x 10(14) molecule cm(-2). For the less volatile species, evidence for multilayer adsorption was observed and the BET isotherm was used instead. The experimental enthalpies of adsorption were consistently higher than the enthalpies of vaporization for all compounds. A linear free-energy relationship was developed between the Langmuir equilibrium constant for adsorption and the compound's (sub-cooled) liquid vapor pressure, providing validation for the use of such relationships in assessing gas-particle partitioning of aromatic hydrocarbons to soot aerosols in the environment. The experimental results were compared to the Junge-Pankow gas-to-aerosol partitioning model.

“…Within literature a numerous number of research papers have considered adsorption processes for single component systems. However, due to complexity of the textile effluent and the variability of the dyeing process little successes have been reported in using this technique as a full scale process to decolourise textile wastewater [1,[6][7][8][9]. Hence, this study was undertaken to address the problems associated with multi component adsorption from aqueous solutions.…”
