Atomic Absorption Spectroscopy: Lab

For AAS measurements, samples must be introduced as clear solutions, often requiring extensive preliminary treatment to dissolve materials like soils, animal tissues, and minerals. Common methods for sample preparation include treatment with hot mineral acids, wet ashing, combustion in closed containers, high-temperature ashing, or fusion with reagents.
Solutions containing organic solvents, such as low-molecular-mass alcohols, esters, or ketones, enhance absorbances by increasing nebulizer...

Adsorption of Gases on Solids

Adsorption of Gases on Solids

Adsorption is a process where molecules, known as the adsorbates, accumulate on a surface, which is referred to as the adsorbent or substrate. Occurring at the solid-gas interface, this phenomenon is crucial in various scientific and industrial contexts. The reverse of adsorption is desorption.Two types of adsorptions exist: physical (physisorption) and chemical (chemisorption). Physisorption involves gas molecules held to the solid's surface by relatively weak intermolecular van der Waals...

Adsorption Isotherms I

Adsorption Isotherms I

Adsorption isotherms are mathematical models that describe how molecules in a gas or liquid phase interact with surfaces. Two of the most common isotherm models are the Langmuir and Freundlich isotherms, which relate to Type I monolayer chemisorption. The Langmuir model is based on four key assumptions:• Adsorption cannot exceed monolayer coverage.• All surface sites are equivalent.• Molecules adsorb only at vacant sites.• There are no interactions between adsorbed molecules.Consider the...

Contact angle measurements.
Adsorption studies on silicon dioxide, stainless steel, and gold surfaces.

Main Results:

Evidence of initial monolayer followed by multilayer asphaltene adsorption.
Adsorption kinetics were surface-dependent and followed Random Sequential Adsorption (RSA) theory for monolayers.
Adsorbed asphaltenes significantly decreased water wettability, reaching a plateau contact angle around 100°.
Brine salinity (3% NaCl) had a minimal effect on wettability alteration.

Conclusions:

Asphaltene adsorption is a complex process influenced by surface material and concentration.
Adsorption significantly alters surface wettability, impacting oil-water interactions in reservoirs.
