Chemical speciation of mercury (Hg) in a wide variety of combustion flue gas matrices has been determined using the mercury speciation adsorption (MESA) method. The MESA sampling system for gas phase Hg species employs a series of heated, solid phase adsorbent traps.

Adsorption is the accumulation of atoms or molecules on the surface of a material. This process creates a film of the adsorbate on the adsorbent's surface. It is different from absorption, in which a substance diffuses into a liquid or solid to form a solution. The term sorption encompasses both processes, while desorption is the reverse process.

There is often confusion between absorbents and adsorbents. Simply put, absorbents work by taking up liquid or gas into spaces within and throughout the material. Adsorbents accumulate liquid or gas on the surface of a solid material. Absorption involves dissolution or diffusion.

Sep 26, 2024 · Absorbency testing is a critical process in evaluating materials' ability to absorb liquids, ensuring quality and performance. Learn about its principles, methods, and significance in laboratory testing. by Trevor Henderson | Sep 26, 2024.

Mar 1, 2023 · Mesa-structures with far-infrared adjustable and enhanced absorption were prepared. Optical constants of Mn 1.56 Co 0.96 Ni 0.48 O 4 films were obtained by spectroscopic ellipsometry. Dielectric functions obtained using classic middle-infrared dispersion relation.

DRIRITE Premium absorbent can be used to provide a quick, simple and easy means to absorb a wide range of liquid spills and leaks around machinery, hoses, pipes, pumps and on general floor areas. It is also handy for other plant housekeeping/safety chores on exterior walkways, drives and dock areas.

Mesa Environmental collects used grease in 55-gallon drums and processes it into a specification fuel through our unique heating and blending methods. We collect oil-saturated absorbents and process the used oil out for reuse.
