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 ...
Activated carbon adsorption of fuel oxygenates MTBE and ETBE from water
The aqueous phase adsorption of fuel oxygenates methyl tertiary butyl ether (MTBE) and ethyl tertiary butyl ether (ETBE) onto commercially available granular activated carbon (GAC; Norit GAC 1240) was investigated in a ...
Recovery of proanthocyanidin from waste of Turkish traditional product, pekmez (molasses)
(Japanese Society for Food Science and Technology, 2007-11)
The possibility of recovering of proanthocyanidin (PA) from the by-product of Turkish traditional product pekmez (molasses) industry, one of the agro industries, was investigated. In order to obtain optimum extraction ...
Moisture sorption and thermal characteristics of polyaramide blend fabrics
Four types of fabrics woven from various polyaramid fibers of Nomex and Kevlar blends were characterized by morphology, XRD, elemental analysis, thermal analysis, and moisture adsorption isotherms. The blends consisted of ...
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 ...
CO2 and N2 adsorption on the acid (HCl, HNO 3, H2SO4 and H3PO4) treated zeolites
CO2 and N2 adsorption on the acid treated natural and synthetic zeolites at 5◦C and 25◦C was studied. The system heterogeneity was higher for CO2 than N2 adsorption and decreased with acid treatment.
Capacity and mechanism of phenol adsorption on lignite
A raw lignitic coal from Soma, Turkey was investigated to determine its potential as an adsorbent for phenol removal from wastewaters. Kinetic batch tests demonstrated that phenol could be completely removed from solution ...
Kinetic estimation of the adsorbate distribution on the surface from adsorbed amounts
A phenomenological multilayer adsorption model for a well-dispersed, homogeneous, nonporous adsorbent and a molecular adsorbate is presented. The model provides explicit kinetic expressions associating the adsorbed amounts ...
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 ...
