Adsorption of anionic polyelectrolyte and comb polymers onto lead magnesium niobate
This paper presents the results concerning the adsorption mechanism of polyacrylic acid (PAA) and polyacrylic acid/polyethylene oxide (PAA/PEO) comb polymer onto lead magnesium niobate (PMN) powders. In the study adsorption ...
Dye adsorption behavior of Luffa cylindrica fibers
Using natural Luffa cylindrica fibers as adsorbent removal of methylene blue dye from aqueous solutions at different temperatures and dye concentrations was investigated in this study. Thermodynamics and kinetics of ...
Clinoptilolite-rich mineral as a novel carrier for the active constituents present in Ginkgo biloba leaf extract
The possible use of clinoptilolite-rich mineral as a novel carrier for the active constituents present in Ginkgo biloba leaf extract solutions was investigated. The flavonoid aglycone constituents were found to be selectively ...
Diffusion mechanism of water vapour in a zeolitic tuff rich in clinoptilolite
The adsorption kinetics of H2O in a clinoptilolite rich zeolitic tuff was experimentally investigated at 18°C. In the identification of the diffusion mechanism the isothermal adsorption model equation was used. It was found ...
Methods of humidity determination Part II: Determination of material humidity
Part II covers the most common methods of measuring the humidity of solid material. State of water near solid surfaces, gravimetric measurement of material humidity, measurement of water sorption isotherms, chemical methods ...
