Activated carbon is processed to have small, low-volume pores that increase the surface area available for adsorption. It has applications in the medical, environmental and energy realms, among others. Since 1962, ASTM International Committee D28 on Activated Carbon has developed standards that play a pre-eminent role in how activated carbon is used. A D28 subcommittee, D28.02 on Liquid Phase…, WK47401, Xylenol Orange Dye, The xylenol orange dye test is a way to determine the relative adsorption rate of unused or reactivated carbons by adsorption of xylenol orange from aqueous solution. This is an important means for deciding which type of activated carbon to use to a specific water treatment application. “Activated carbon performance can roughly be defined as a combination of the ability to adsorb a particular…, WK47421, Particle Size Distribution, Mercury flue gas, home water filters and potable water treatment are the main applications in which powdered and fine mesh carbons are used.
