Sorbent Membranes: Determination of Sorption Capacity and True Membrane Permeability
Artificial Organs, 1980ABSTRACTSorbent membranes are designed to meet the requirements for extracorporeal treatment of body fluids. These membranes offer the possibility of combining hemodialysis and hemoperfusion in a single device. Transport of solutes with both sorption and dialysis occurs simultaneously in a sorbent membrane dialyzer.

Specific 137Cs-sorption capacity parameters of soils and mineral sorbents
Eurasian Soil Science, 2008The selective sorption of cesium by some soils, minerals, and natural mineral sorbents was studied using new methodological and experimental approaches. It was found that the total capacity of two types of highly selective sorption sites significantly differing (by several orders of magnitude) in the selectivity coefficients of Cs-K ion exchange makes ...

Fluidized bed calcium looping: The effect of SO2 on sorbent attrition and CO2 capture capacity
Chemical Engineering Journal, 2012The CO2 capture capacity and the extent of particle attrition during simulated calcium looping cycles in a fluidized bed were studied, with a focus on the influence of SO2 in the flue gas. Five calcination/carbonation cycles (calcination at 850°C and 20% CO2, carbonation at 700°C and 16% CO2) were carried out with a reference limestone using different ...

Effect of interlayer anion on the CO2 capture capacity of hydrotalcite-based sorbents
Separation and Purification Technology, 2019Abstract A series of hydrotalcites (HTCs) samples with different compensating anions was prepared (several anions never used before). The physicochemical characterization of these materials was realized through several techniques (including XRD and SEM/EDS).

The effect of relative humidity on CO2 capture capacity of potassium-based sorbents
Korean Journal of Chemical Engineering, 2011Potassium-based sorbent was prepared by impregnation with potassium carbonate on activated carbon. The role of water and its effects on pretreatment and CO2 absorption was investigated in a fixed bed reactor. K2CO3 could be easily converted into K2CO3·1.5H2O working as an active species by the absorption of water vapor as the following reaction: K2CO3 ...

Comparing the arsenic sorption capacity of Bauxsol‚Ñ¢ and its derivatives with other sorbents
2005In view of the frequency of occurrence of groundwaters with high arsenic contents in many countries, including several of the poorest developing countries, the development of an inexpensive and efficient system for arsenate removal from drinking water is essential.

A lean method for determination of dynamic capacity of a sorbent at multiple sorption of cations
International Journal of Environmental Science and Technology, 2019A lean method for calculation of the dynamic capacity of a sorbent as the time function has been suggested that employs a limited amount of experimental data for a sorption process of any duration and allows to obtain an analytical solution by quadrature.

Characterization and stability of a new, high-capacity amine-functionalized CO2 sorbent
International Journal of Greenhouse Gas Control, 2013Abstract Solid sorbents have received extensive research as an alternative to aqueous amine scrubbing to remove CO 2 from gas streams due to their theoretically lower energy requirements. Amine-functionalized sorbents are among the solid sorbents with the highest CO 2 capacity. In this study, a recently developed amine-functionalized sorbent with a

Structure Effects of Potassium-Based TiO2 Sorbents on the CO2 Capture Capacity
Topics in Catalysis, 2010The CO2 absorption properties of potassium-based TiO2 sorbents prepared by calcining at various temperatures from 300 to 700 °C under N2 and air were investigated in a fixed bed reactor at 60 °C. The CO2 capture capacity of the sorbent was changed dramatically depending on the structure of the sorbent, which was affected by calcination atmosphere, as ...
