VILLABONA, Ángel; TEJADA, Candelaria  e  TEJEDA, Lesly. ADSORTION OF DIESEL IN AQUEOUS SOLUTION ON CEDAR ASERRIN (CEDRELA ODORATA L.) IN FIXED BED COLUMN. Investig. andina [online]. 2017, vol.19, n.35, pp.31-44.  Epub 26-Nov-2018. ISSN 0124-8146.

The use of Cedar sawdust (Cedrela odorata L.) in the adsorption of diesel in aqueous solution was evaluated. Sawdust adsorbent potential in continuous system was analyzed, varying the amount of biomass and the flow rate, using transparent plastic columns of diameter 3.5 cm and 18.5 cm height, with a contact time of 180 min, taking aliquots of 50 mL in different intervals; the measurement of residual concentration was made through gas chromatography, finally, saturation of the column at the best conditions was established. Determining that at 600 minutes balance is reached, in which a high saturation of the biomass possibly occurs, reaching a capacity of 62.93mg / g determined with the Thomas model at a flow of 0.1 mL / s. 4 g of cedar sawdust.
