Adsorption of Benzene and Toluene from Aqueous Solution onto Granular Activated Carbon

Abstract

The liquid-phase adsorption of benzene and toluene on granular activated carbon TOG 20 × 50 has been studied at (303.15, 313.15, and 323.15) K. The temperature dependent forms of the Toth and Sips equations were used to correlate the experimental data. Excellent agreement between the experimental data and those two equations are observed.

Organic xenobiotics removal in constructed wetlands, with emphasis on the importance of the support matrix

“…A small illustrative sample of the tests that have been conducted to study the adsorption of organic pollutants by activated carbon is presented in Table 2. Among the most commonly tested organic substances, several examples can be found including dyes [141][142][143][144][145][146], phenolic compounds [147][148][149], pesticides [150][151][152][153][154], pharmaceuticals [155][156][157][158] and many other organic pollutants [159][160][161].…”

Adsorption Isotherm of Dibenzyl Toluene and its Partially Hydrogenated Forms Over Phenyl Hexyl Silica

“…Additionally, the bi-Langmuir adsorption isotherm (eq (6)) was used to correlate the experimental data by assuming the maximum loadability equal for all components in the system [14,15]. model (with 8 parameters) were used to correlate the experimental data.…”

“…Several equations for correlating single component adsorption data such as Freundlich, Langmuir and combined Langmuir-Freundlich (also known as Sip's equation) were evaluated for the correlation of the experimental data. The Freundlich isotherm with two parameters is given by eq (2) [14,15].…”

“…Where q sat is the saturation capacity of monolayer and b is second Langmuir parameter which quantifies the adsorption energy H ads using eq (4) [14]. …”

β-cyclodextrin-MCM-41 silica as promising adsorbent for the trace amounts removal of aromatics from water

“…There are a variety of chemical and physical methods that have been suggested for the purification of wastewaters from aromatics. Among them the common used are adsorption [4][5][6][7][8][9][10][11][12][13][14][15], bio-and photodegradation [16,17], solvent/surfactant extraction [18,19], chemical oxidation [20], membrane treatment [21], and coagulation-floculation [22]. However, adsorption has been shown to be one of the most effective procedures in the elimination of benzene and its derivatives from aqueous solutions.…”
