Both materials are based on finely-ground activated carbon with a particle size of D50 = 0.8 μm which is quasi-soluble, i.e. it forms stable colloidal solutions in water over a wide concentration range. With these activated carbon colloids, an approved material of environmental technology is now applicable for injection into contaminated aquifers to form sorption barriers by controlled deposition on aquifer sediment directly in the flow passages. A new remediation strategy can be followed – the in-situ generation of a permeable AC sorption barrier in contaminated aquifers. Based on the colloidal carbon particles, a second material has been developed which combines the sorption properties of the activated carbon carrier and the reactivity of the zerovalent iron deposits. This CARBO-IRON (20 wt-% zero-valent iron) has proved its suitability as a dehalogenation reagent applicable for both plume and source treatment.</p></abstract><publication_date><month>04</month><day>29</day><year>2013</year></publication_date><pages><first_page>54</first_page><last_page>61</last_page></pages><publisher_item><identifier id_type="pii">506</identifier></publisher_item><doi_data><doi>10.30955/gnj.000506</doi><timestamp>1714009882</timestamp><resource>https://journal.gnest.org/publication/506</resource></doi_data></journal_article></journal></body></doi_batch> </div>
