PEI-DTC Technical White Paper: A Next-Generation Polymeric Heavy Metal Collector for Industrial Wastewater Treatment and Metal Recovery
PEI-DTC is a next-generation polymeric heavy metal collector built on a polyethyleneimine backbone grafted with hundreds to thousands of dithiocarbamate groups. It integrates electrostatic attraction, multidentate chelation, polymer bridging and rapid flocculation in a single reagent, offering superior removal efficiency, broad pH applicability, fast settling, lower sludge volume and metal-recovery potential compared with hydroxide, sulfide, Na-DDTC, TMT and xanthate precipitation technologies.
