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 29 Sep 2022 19:47:43 SAST ]]> Characterization of manganese tetraarylthiosubstituted phthalocyanines self assembled monolayers https://commons.ufh.ac.za/vital/access/manager/Repository/vital:53621 Sat 23 Jul 2022 20:56:30 SAST ]]>
