Voltammetry of microparticles, an electrochemical methodology based on the record of the voltammetric response of sparingly
soluble solids mechanically transferred to the surface of inert electrodes in contact with suitable electrolytes, is able
to provide significant analytical information in the fields of conservation and restoration of cultural goods. Using this
methodology, identification, speciation, and relative and absolute quantification of analytes from works of art samples can
be achieved. Applications to the analysis of organic and inorganic pigments in paints, fibbers, ceramic materials as well
as alteration compounds in paintings and metallic artifacts are reviewed. 相似文献

In the 1950s and 1960s fundamental developments in electrochemical methods included voltammetry and low signal techniques. A generation later, the discovery of the unusual properties of ultramicroelectrodes has opened new possibilities of analyzing electrode processes. The changes in mass transport conditions bring about extremely high current densities at ultramicroelectrodes, whereas the currents themselves become very small. This little-noticed phenomenon allows for many electroanalytical applications that are not possible with conventional electrodes, especially experiments in solutions with very low electrolyte concentrations, in nonpolar solvents, in solids, and even in gases. In addition, two factors— changes in the experimental time scale at low scan rates because of the size of the electrode, and insignificant iR effects at very high scan rates—make it possible to study very fast homogeneous and heterogeneous electrode processes. 相似文献
