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. A proposed new test method will describe how a laser light scattering technique can determine the particle size distribution of fine mesh activated carbon. ASTM member Neal Megonnell, vice president, sales and marketing, Haycarb USA, says the proposed test…, ASTM Committee D28 Next Meeting:, April 27, April Committee Week, Anaheim, Calif., Technical Contact:, (WK47401) Adam Redding, Ph.D., Evoqua Water Technologies LLC, Northwest, Pa., tel +1.724.719.0805; adam.redding@evoqua.com and (WK47421) Neal E.

In a quest for lighter, more crash-resistant and fuel-efficient vehicles, the automobile and steel industries are developing steel sheets that have higher alloy content, and thus more complex hardening mechanisms, than sheets currently being used. The sheets, known generally as advanced high-strength steels, are covered by a new ASTM International standard, ASTM A1079 , Specification for Steel…, ASTM Committee A05 Next Meeting:, Nov. 11-13, November Committee Week, Atlanta, Ga., Technical Contact:, Gary Dallin, GalvInfo Center, International Zinc Association, Burlington, Ontario, Canada, Phone: 905-315-7443; gdallin@cogeco.ca, ASTM Staff Contact:, Kristy Straiton, Phone: 610-832-9640; kstraiton@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org R elease #9304

Mercury emissions from flue gases in coal-fired power plants are a large source of atmospheric mercury in the United States, but no standard for determination of mercury adsorption currently exists. One promising method of controlling these emissions involves the injection of powdered activated carbon into the flue gas. A proposed new ASTM International standard would evaluate the performance of…
