Note that an isotherm that is favorable for adsorption is unfavorable for desorption. In particular, the most favorable isotherm is the most difficult to desorb — hence the name irreversible. 30°C 0°C absorption the sharing of indirect costs or OVERHEADS to units of product by means of COST RATES.Provided that actual overheads do not exceed BUDGET and that actual output is the same as budgeted output, then the overhead cost rate should allow total product cost to be determined, and a selling price set which will recover the overhead costs involved in producing and selling the product. Adsorption meaning.There are 1 meaning(s) of Adsorption.the accumulation of molecules of a gas to form a thin film on the surface of a solid 2011-10-01 The need to design low-cost adsorbents for the detoxification of industrial effluents has been a growing concern for most environmental researchers. So modelling of experimental data from adsorption processes is a very important means of predicting the mechanisms of various adsorption systems. Therefore, this paper presents an overall review of the applications of adsorption isotherms, the use adsorption meaning.

Conversely it also means that the extent of adsorption increases when the temperature is reduced. Effect of Pressure of the Gas phase Adsorption empirical kinetic models and mass transfer kinetic models were reviewed. • The physical meanings and applications of 16 adsorption kinetic models were analyzed. • The model validity evaluation equations were summarized based on literature.

The reverse of adsorption or absorption. Adsorption of polyelectrolytes on to insoluble calcium 167 and barium 129, 164, 168 salts occurs to a significant extent over a wide range of pH, with added electrolyte enhancing the adsorption particularly in the higher pH range. 129 Van Lierde 169 found less sodium polyacrylate adsorbed on to dolomite on increasing the pH above pH 7.

Adsorption and absorption, the Latin term referring to absorption in the bulk of the solid, are subsumed under the general term sorption. The phenomenon of adsorption first came under study in the late 18th century by Scheele (1773), though there is no question that adsorption had been used by humanity in practical activities from time immemorial. Adsorption is a term which is completely different from Absorption .While absorption means uniform distribution of the substance throughout the bulk, adsorption essentially happens at the surface of the substance. When both Adsorption and Absorption processes take … adsorption. The ultimate in favorable isotherms is irrevers-ible adsorption, where maximum adsorption is reached at very low partial pressures. Note that an isotherm that is favorable for adsorption is unfavorable for desorption.

Adsorption is a surface phenomenon where the molecules simply attach to the surface of the adsorbent. Principle Adsorption seems to share the same meaning with sorption. Cite. 1 Recommendation. 9th Oct, 2018. Amir Behravan.
