Hydrogel recovers anions from wastewater

Article Abstract:

Researchers at the University of Maryland have developed a packed-bed sorption process for the removal and recovery of phosphate, nitrate, nitrite, sulfate, sulfide and perchlorate anions from wastewater. The process uses a crosslinked poly(allyl amine hydrochloride) polymeric hydrogel as the sorbent. The hydrogel selectively binds with the pollutant and toxic anions into the polymer matrix, allowing for its subsequent removal from the contaminated system.

Hazwaste manifesting goes electronic

Article Abstract:

The US Environmental Protection Agency has unveiled a proposal to alter the Uniform Hazardous Waste Manifest system. Under the proposal, the agency seeks to establish standard forms and procedures and to permit waste handlers the choice of using an electronic manifest. The change will allow waste handlers to conduct nearly all the waste tracking and recordkeeping functions of the manifest electronically.
