Description
Mengxin Tu and co-authors use electron beam radiation to break apart a lead compound that poisons industrial wastewater. Lead bound to EDTA slips past standard cleanup, since the cage keeps the metal dissolved and mobile. A method that cracks the cage and recovers the metal in one pass would solve two problems.
Beam tests show a mild dose clears over ninety percent of the compound, though most lead stays caged at that stage. A stronger dose lifts compound loss a bit more and frees near seventy percent of the lead as metal. Radical trapping tests pin the work on hydroxyl radicals that chew the cage down to small acids. Leftovers test as far less toxic than the start mix. Beam plants could thus detox water and reclaim lead together.
