β¦ Synopsis
A series of 12 macrocycles containing 4, 6, or 8 N, S, and 0 heteroatoms (with increasing size from 14 to 24 atoms in the cycle) was studied to ascertain size and heteroatoms effects on the formation and redox characteristics of their mercuric complexes. The concentration dependence o f anodic currents at mercury electrodes in solutions of these ligands led to the determination of the formation constants of the complexes generated according to the following scheme: kfgGflg'+ + ~L J -, ~g ' + + j I 2 s ( t $ & ) ' + 22N6C4 [16], 24N6C5 [I%], and 24N602 [17b].

A general study of the anodic oxidation of mercury in the presence of ethane-1,2-bismercaptoacetic acid (ebma) is made by different polarographic techniques (dc,, dp and ac), cyclic voltammetry and coulometry at constant potential. The anodic process involves the reversible and diffusion-controlled
Anodic charging curves have been measured by the galvanostatic technique on Bi in O-05 M solutions of NalSOc, NalCOI and NaOH at 30Β°C. Oxide iilms can be grown to 100 V and more. The nature of the fihn depends on the pH and the type of anion present. Formation rates are highest in sulphate solutions

The anodic oxidation of mercury in the presence of 2.2'~thiobisacetic and 3,3'-thiobispmpanoic acids has been studied by dc,, dp, act and uc, polarography, cyclic voltammetry and coulometry. The electrode processes include the overall formation of the HgL$-complexes, through the dispropertionation o
