Development of an electrochemical sensor based on nanostructured hausmannite-type manganese oxide for detection of sodium ions
The preparation and electrochemical characterization of hausmannite-type manganese oxide to use as a sensing material for sodium ion is described. This paper reports a new via synthetic to obtain of the hausmannite-type ...
Manganese determination by GFAAS in feces and fish feed slurries
This paper presents a simple, fast and sensitive method to determine manganese in samples of feces and fish feed by graphite furnace atomic absorption spectrometry (GFAAS) by the direct introduction of slurries into the ...
SYNTHESIS AND CHARACTERIZATION OF MANGANESE- COBALT SOLID SOLUTIONS PREPARED AT LOW TEMPERATURE
(Sociedad Chilena de Química, 2010)
Geologia e Caracterização Tecnológica do Minério de Manganês da Mina Córrego do Cocho, Itapira (SP)
The objects of this study are three manganese ore deposits and one mine derived from lateritic weathering of gondites (spessartine quartzites). These deposits are associated with Mn-rich garnet metasediments of the Itapira ...
Voltammetric performance and application of a sensor for sodium ions constructed with layered birnessite-type manganese oxide
(Elsevier B.V., 2009-12-15)
The preparation and electrochemical characterization of a carbon paste electrode modified with layered birnessite-type manganese oxide for use as a sodium sensor is described. The effects of powder synthesis process (sol-gel ...
