Voltammetric determination of agriculturally-significant benzenearsonic acids

Applied Polarography and Voltammetry of Organic Compounds in Pratical Day-To-Day Analysis Part II

“…As the peak potentials are close together at -0.7 to -1.04 V vs. SCE in solutions containing hydrochloric acid and sodium chloride of pH 0.5 to 1.6, simultaneous determination is difficult without a separation step. 565 The development of precise, selective, and sensitive methods for trichothecenes determination in naturally contaminated foodstuffs is of fundamental importance for environmental and health protection. A systematic investigation has recently been initiated by Palmisano et al 566566a in order to assess the potentialities of d.p.p.…”

Determination of Roxarsone Using Carbon Paste and Amberlite LA2 Modified Carbon Paste Electrodes

“…Among these, electrochemical techniques are the methods of choice. Aromatic organoarsenic compounds have been thoroughly studied by polarography [11± 14] and differential pulse polarography [15]. However, the application of modern voltammetric methods using carbon paste electrodes has not yet been reported.…”
