“…Analyses of the equilibrium data for the biosorption of Direct (SB) and Reactive (CR) dyes onto raw P. oceanica fibres have been undertaken using the Langmuir (1918), Freundlich (1906) and Redlich-Peterson (Jossens et al 1978) models, which are commonly used for describing adsorption equilibrium associated with the treatment of dye-containing effluents.…”

ABSTRACT:The adsorption of two textile dyes onto a low-cost and unexploited marine biomass, Posidonia oceanica (L.), was investigated in batch mode. The biosorption process was studied as a function of contact time, initial pH and temperature. The highest dye adsorption capacities attained at 30°C were 3.081 mg/g at pH 2 for the Direct dye and 4.252 mg/g at pH 5 for the Reactive dye. The Freundlich, Langmuir and Redlich-Peterson adsorption models were used to determine the parameters of the equilibrium data and, under the operating conditions studied, the best fit to the experimental curves was obtained using the Freundlich model. The thermodynamic constants of the adsorption process (i.e. ∆G 0 , ∆H 0 and ∆S 9) were evaluated as -6.36 kJ/mol, 57.80 kJ/mol and -103.45 J/(mol K), respectively, for the Direct dye and as -3.22 kJ/mol, 84.10 kJ/mol and -225.55 J/(mol K), respectively, for the Reactive dye. Consequently, the adsorption of dyes onto P. oceanica biomass was favourable, endothermic and spontaneous.

A theoretical description of recently published paracetamol adsorption data on a series of non-modified commercial activated carbons is presented. Nineteen of the most widespread adsorption isotherm equations are analysed and the resulting maximum adsorption values compared. The equations proposed by Weber and Vliet, by O'Brien and Myers as well as by Dubinin and Astakhov led to the highest values of the average correlation coefficient describing the fit of the theoretical data to those obtained experimentally. On the basis of the results obtained as well as those published previously, the importance of carbon surface basic groups and carbonyl groups in the mechanism of paracetamol adsorption is emphasised.

“…Also, the Redlich-Peterson equation (Redlich and Peterson, 1959) approaches the Freundlich at higher levels and is also consistent with Henry's Law. An adaptation of the Langmuir equation for heterogeneous surfaces, the Toth equation (Toth, 1962), has demonstrated good fit to data and is thermodynamically sound (Jossens et al, 1978). Other models, consisting of three and five parameters have also been used (Radke, 1972).…”
