Immobilization of Cr(VI) by sulphate green rust and sulphidized nanoscale zerovalent iron in sand media: batch and column studies

摘要

Experimental set-up used for measuring breakthrough curves under strictly anoxic conditions (1.) on-line by solution absorbance using a UV–Vis flow through cell connected to an UV–Vis spectrophotometer; (2.) manual collection to determine Cr(VI) via 1,5-diphenylcarbazide colorimetric method, and Crtot and Fetot via ICP-OES
