Adsorbents

Purolite polymeric adsorbent resins are high-porosity synthetic spherical beads, typically used for the purification and extraction of target molecules in aqueous solutions. Purolite adsorbents are safe and efficient because toxic solvents and expensive distillation and precipitation processes are not required for effective compound extraction. Also, unlike other adsorption technologies, additional benefit of recyclability is provided. For maximum adsorption, the polymeric adsorbent resins have high internal surface area, high porosity and controlled pore size distribution.

Purolite has two families of adsorbents, PuroSorb™ (non-functionalized divinylbenzene and acrylic polymers) and Macronet™ (hyper-crosslinked, functionalized and non-functionalized styrenic polymers). These product lines are offered in a broad range of matrices, porosities and pore sizes that make them ideal for a variety of industrial applications.
