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.

While the use of digital evidence is fairly common in contemporary criminal investigation, there are still relatively few degree programs in computer forensics. A new standard developed by ASTM International Committee E30 on Forensic Sciences provides a road map for post-secondary institutions to develop degree programs in computer forensics. The new standard, ASTM E2678 , Guide for Education and…

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…

No industry standard currently exists that addresses the vacuum sealing requirements of knife-edged flanges for high vacuum applications. Existing international standards focus on interchangeability of the hardware, but do not address the reliability of the seal. ASTM International Committee E42 on Surface Analysis is now working on a proposed standard on the subject, WK21206 , Specification…
