Complexes of lead, copper and bismuth with resorcinol showed the largest increase in current with increase in metal concentration, whereas complexes of these metals with 4-t-butylcatechol showed the lowest current response. Cadmium showed a different behaviour from the other three metals in that the highest current response was observed with 4-methylcatechol. The four metals could be determined simultaneously in the presence of resorcinol, although considerable interference was observed between bismuth and copper.]]> Thu 16 May 2024 05:11:04 SAST ]]> Voltammetric behavior of cysteine and metallothionein on cobalt (II) tetrasulfonated phthalocyanine modified glassy carbon electrodes https://commons.ru.ac.za/vital/access/manager/Repository/vital:57077 Thu 16 May 2024 05:11:03 SAST ]]> Applications of polymerized metal tetra-amino phthalocyanines towards hydrogen peroxide detection https://commons.ru.ac.za/vital/access/manager/Repository/vital:53451 Thu 16 May 2024 05:04:11 SAST ]]> Electrooxidation of hydrazine catalyzed by noncovalently functionalized single-walled carbon nanotubes with CoPc https://commons.ru.ac.za/vital/access/manager/Repository/vital:53904 Thu 16 May 2024 05:04:10 SAST ]]> Melatonin protects against copper‐mediated free radical damage https://commons.ru.ac.za/vital/access/manager/Repository/vital:56654 Thu 16 May 2024 05:04:10 SAST ]]> Critical assessment of the quartz crystal microbalance with dissipation as an analytical tool for biosensor development and fundamental studies https://commons.ru.ac.za/vital/access/manager/Repository/vital:54521 Thu 16 May 2024 05:04:09 SAST ]]> Characterization of manganese tetraarylthiosubstituted phthalocyanines self assembled monolayers https://commons.ru.ac.za/vital/access/manager/Repository/vital:53621 Thu 16 May 2024 05:04:08 SAST ]]> Synthesis, electrochemical characterization of tetra-and octa-substituted dodecyl-mercapto tin phthalocyanines in solution and as self-assembled monolayers https://commons.ru.ac.za/vital/access/manager/Repository/vital:53743 Thu 16 May 2024 05:04:08 SAST ]]>
