[Adsorption of amino acids onto hydroxyapatite].
The interaction of Hydroxyapatite (HAP) with organic molecules is of biological importance, since the former is considered as the prototype mineral found in calcified tissues, such as bone and teeth. Some proteins display a high affinity for HAP and they are involved in the mineralization of bone. Another important aspect in biological systems is the role that various molecules play as inhibito...
متن کاملAdsorption Kinetics of Phenolic Compounds onto Activated Carbon
Aqueous-phase edsorption equilibrium and kinetic mechanism of phenol, 3-chlorophenol rnd o-cresol onto Norit Granular Activaied Caibon (NAC 1240) were studied in a batch system at temperature of 30 oC, agitation speed of 120 rpm, initial phenol concentrations of 25-200 mg/t. The elfects of initid phenol concentration and time of adsorption on phenol adsorption process were lnvestigated. The ads...
متن کاملKinetic and Isotherm Modelling of the Adsorption of Phenolic Compounds from Olive Mill Wastewater onto Activated Carbon.
The adsorption of phenolic compounds from olive oil wastewater by commercial activated carbon was studied as a function of adsorbent quantity and temperature. The sorption kinetics and the equilibrium isotherms were evaluated. Under optimum conditions (8 g of activated carbon per 100 mL), the maximum sorption capacity of activated carbon expressed as mg of caffeic acid equivalent per g of activ...
متن کاملKinetics of adsorption of carboxylic acids onto titanium dioxide.
A FTIR-ATR kinetic study on the adsorption of carboxylic acids (oxalic, citric, malonic, succinic, gallic, EDTA and TTHA acids, where EDTA = ethylenediaminetetraacetate and TTHA = triethylenetetramine-N,N,N',N'',N''',N'''-hexaacetate, in the concentration range 6 x 10(-7) M-2 x 10(-5) M on TiO(2) (Degussa P25) by ATR-FT-IR is reported. The influence of carboxylic acid concentration, pH, ionic s...
متن کاملAdsorption of "soft" spherical particles onto sinusoidally-corrugated substrates.
We utilize a Monte Carlo simulation scheme based on the bond fluctuation model to simulate settlement of "soft" adhesive particles onto sinusoidally-corrugated substrates. Particles are composed of a hard inner core with a "soft" adhesive shell made of surface-grafted polymer chains. These chains adhere to surface lattice sites via pair wise non-specific interactions acting between the substrat...
