VOLTINT: A Matlab®-based program for semi-automated processing of geochemical data acquired by voltammetry

The effect of pH and natural microbial phosphatase activity on the speciation of uranium in subsurface soils

“…The Mn 2+ calibration curves were used to elucidate the concentrations of other species with the pilot ion method (Brendel and Luther, 1995). All voltammetric data were integrated using a semi-automated software developed for these applications (Bristow and Taillefert, 2008).…”

The flux of soluble organic‐iron(III) complexes from sediments represents a source of stable iron(III) to estuarine waters and to the continental shelf

“…The current height of the Fe(III)-1N2N complex was measured at 20.48 V vs. Ag/ AgCl. Data from voltammetric scans were integrated using VOLTINT, a semiautomated integration software implemented in Matlab (Bristow and Taillefert 2008). A conditional binding constant of 1.42 3 10 15 for the competitive ligand 1N2N was determined by calibration with ethylenediaminetetraacetic acid in the buffer system (10 mmol L 21 PIPES, 0.25 mol L 21 NaCl) used in all measurements (Rue and Bruland 1995).…”

Siderophores Are Not Involved in Fe(III) Solubilization during Anaerobic Fe(III) Respiration by Shewanella oneidensis MR-1

“…A scan rate of 200 mV s Ϫ1 from Ϫ0.1 to Ϫ1.8 V with a pulse height of 0.05 V was used as previously described (10,59,60,62 ) by CSWV in degassed medium, and the pilot ion method was used to quantify concentrations of Fe(II). Voltammograms were integrated using a semiautomated software program developed for these applications (6). Initial rates of soluble organic Fe(III) production were determined by linear regression of the increase in soluble organic Fe(III) current intensities for 24 h (disregarding any initial lag period).…”
