General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Click here for more details.

Application

Activated charcoal (DARCO®, 20-40 mesh particle size, granular) can be used in the selective adsorption of phenanthrene with an excellent selectivity of ~74. It can also be used in the adsorption of metals like lead, copper, cobalt, and chromium from aqueous solution.[1]

Other Notes

Acid-washed lignite carbon for general uses.
