Title A name given to the resource Reciclagem do crômio de resíduos químicos provenientes da determinação de carbono oxidável em fertilizantes orgânicos Creator An entity primarily responsible for making the resource Jeane M. C Machado, Lenita M. C. P. E Oliveira, Marcos Y. Kamogawa Description An account of the resource This work proposes a separation, recovery and reuse procedure of chemical residues with chromium. This residue was generated by the determination of oxidizable carbon in organic fertilizers samples. The Cr(VI) of the residue was reduced with ethanol and precipitated with NaOH. The Cr(OH)3 precipitate was separated and oxidized to dichromate ions with hydrogen peroxide. This solution was used another time in organic carbon determination. The uses of recycled dichromate solution were appropriated in four successive recycling. The accuracy was proven using potassium hydrogen phthalate and ten organic fertilizer samples. The organic carbon results, determined with recycled solutions, were similar the conventional solution. Date A point or period of time associated with an event in the lifecycle of the resource 2011 Subject The topic of the resource dichromate ion, organic carbon analysis, recycling Identifier An unambiguous reference to the resource within a given context 10.1590/S0100-40422011000100024 Source A related resource from which the described resource is derived Química Nova Publisher An entity responsible for making the resource available Sociedade Brasileira de Química Coverage The spatial or temporal topic of the resource, the spatial applicability of the resource, or the jurisdiction under which the resource is relevant Chemistry Relation A related resource <a href="http://www.scielo.br/scielo.php?script=sci_arttext&amp;pid=S0100-40422011000100024&amp;lng=en&amp;tlng=en" target="_blank" rel="noreferrer noopener">http://www.scielo.br/scielo.php?script=sci_arttext&amp;pid=S0100-40422011000100024&amp;lng=en&amp;tlng=en</a>
