Sentence examples for adsorbents from inspiring English sources

Solids that are used to adsorb gases or dissolved substances are called adsorbents; the adsorbed molecules are usually referred to collectively as the adsorbate.

The resultant yellow to light brown liquor is further decolorized by carbon adsorbents, such as granular activated carbon or bone charcoal, or by ion-exchange resins of acrylic or styrenic materials.

Popular adsorbents are silica and alumina, which both retain polar compounds.

Modern practice speeds up this process by adding excess tannin, clarifying with protein or tannin adsorbents, or using enzymes to degrade the proteins.

Purification methods consist of chemical treatment, decolorization by adsorbents, and fractionation of the separated waxes into grades by distillation, recrystallization, or both.

When the water is removed from the pores, these substances become selective adsorbents for gas molecules of certain sizes and shapes.

Physical adsorption resembles the condensation of gases to liquids and depends on the physical, or van der Waals, force of attraction between the solid adsorbent and the adsorbate molecules.

Pollutants can be collected by passing samples of air through a tube containing an adsorbent material.

Silica gel was known as early as 1640, but it remained a curiosity until its adsorbent properties were found useful in gas masks during World War I.

The methods are then further subdivided in terms of the stationary phase; thus, if the stationary phase is a solid adsorbent, there are methods such as gas-solid chromatography (GSC) and liquid-solid chromatography (LSC).

One important method is liquid-solid chromatography in which the porous adsorbent is polar and separation is based on the properties of classes of compounds e.g., amines (alkaline) from alcohols (neutral) and esters (neutral) from acids.
