AB The objective of this work was to study Cr(VI) sorption/desorption on twoby-products from the wood industry: pine sawdust and oak wood ash. The retention/releaseexperiments were carried out using standard batch-type trials. In the sorption-phaseexperiments, pine sawdust showed 23% sorption when a concentration of 100 mg Cr(VI)L−1was added, whereas sorption on oak wood ash was 17%. In the desorption-phase,chromium release was clearly higher from pine sawdust than from oak wood ash (98% and66%, respectively). Sorption curves were well fitted to the Freundlich and Lineal models.In view of the results, both materials can be considered of very limited value to remove Crfrom polluted soil and water, which can be of relevance regarding its appropriate use asbiosorbents and recycled by-products.
