Ethylene Glycol Treatment of Scots Pine (Pinus Sylvestris) Sawdust to Produce a Novel Adsorption Material for Chromium(VI)

D.K. Sidiras & D.V. Politi
Batch and column kinetics of Chromium (VI) adsorption on (i) ethylene glycol/water and (ii) ethylene glycol/water/sulphuric acid treated Scots Pine (Pinus Sylvestris) sawdust was simulated, using untreated pine sawdust as control, in order to explore the potential use of this low-cost adsorbent for wastewater Chromium (VI) removal. The effect of the pretreatment time at 200 oC on the microstructure and the crystallinity of pine sawdust was investigated using scanning electron microscope (SEM), Fourier transform infrared...
