Characterization and adsorption capacity of Brazilian kaolin
Journal of Radioanalytical and Nuclear Chemistry, 2021This study has evaluated chemical, radiological composition and determined the cation exchange capacity (CEC) for three commercially available Brazilians raw kaolins. The mineralogical characterization indicated the presence of kaolinite, kaolinite and quartz and pirophylliteas the mains mineral constitution of the samples.

Permeability and Adsorption Capacity of Dialysis Membranes to Lipid A
The International Journal of Artificial Organs, 1997Hemodialysis membranes were tested in vitro for possible penetration by low molecular weight endotoxins containing lipid A. Using lipid A from Escherichia coli as a model substance for this kind of pyrogen, different dialyzers (F4, E3, Acepal 1300, Altraflux, F 40, Polyflux 110, Filtral 12, F 60) were challenged by tangential filtration in aqueous ...

Adsorptive Capacities of Hemoperfusion Devices in Clinical Use
Artificial Organs, 1978ABSTRACTFive different hemoperfusion devices have been used in the treatment of patients intoxicated with barbiturates. The changes in drug clearance values which occurred during hemoperfusion varied according to the device used. Even after very long periods of hemoperfusion, however, drug clearance values never fell to zero.

High capacity oil adsorption by graphene capsules
Nanoscale, 2017Compared to the space between graphene sheets, the entrance to the graphene capsule inner space is very limited, which can lead to stable oil adsorption with a larger capacity.

Dynamic adsorption of ammonia: apparatus, testing conditions, and adsorption capacities
Measurement Science and Technology, 2017Abstract There is a growing need for adsorbents with high capacities for adsorption of toxic gas molecules. Methods and conditions to test these materials introduce large discrepancies and overestimates (~90%) in the reported literature.

Residual adsorption capacity of carbon beds
Carbon, 1984Abstract The retention time of a small (0.3 cm 3 ) ethane pulse, to which various dry weights (1–3 g) of activated carbon were exposed, was studied as a nondestructive method of determining the residual adsorption capacity of the bed. Carbon beds, partially saturated with CCl 4 or water, adsorbed the ethane from and then desorbed the ethane into the

Adsorption capacity of hydrogen isotopes on mordenite
Fusion Engineering and Design, 2008Abstract In a fusion reactor system, a monitoring of hydrogen isotopes including tritium is necessary for the safety of system control and operation. A gas chromatography using a cryogenic separation column is one of the methods for hydrogen isotope analysis. Synthesis zeolite such as molecular sieve 5A (CaA) is a candidate material of the separation

Adsorption capacity in saturated liquid mixtures
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1998Abstract The adsorption capacity of carbonaceous adsorbents was estimated by wetting in a saturated binary mixture, containing n-heptane and methanol. The measurements were performed volumetrically using specially constructed equipment. The results were compared with the adsorption capacity derived from nitrogen adsorption data.

The adsorptive capacity of cotton for sodium oleate
Journal of the American Oil Chemists' Society, 1949SummaryThe adsorption of soap on cotton from solutions of pure sodium oleate has been investigated. The adsorbate has been shown to be an acid soap of the composition 1 NaO1: 1 HO1. The addition of free sodium hydroxide represses hydrolysis and reduces the adsorption.

Activated Carbon Adsorption Capacities for Vapors
Carbon, 1992Abstract It is sometimes desirable to estimate the adsorption capacity of an activated carbon bed for a chemical vapor at a selected concentration. The laboratory measurement of such a capacity (one point on an adsorption isotherm) may be hindered due to toxicity, availability, cost, time, etc.
