A new type of a.e. wave that occurs in some supporting electrolytes (e.g., sulfate, nitrate, perchlorate) at high positive polarizations of the dropping mercury electrode is described. It has been named "predissolution wave" because it occurs at potentials of the beginning mercury dissolution. The wave is due to the exceeding of the solubility product of the mercurous salts of the respective anions. On the addition of salts whose anions form complexes with mercurous ions (e.g., thiosulfate, thiocyanate, sulfite), the peak of the wave shifted to more positive potentials and increased in height because of the solubilization of the film at the electrode surface. It was also found that the in-distinct a.c. wave obtained in thiosulfate solutions at +0.19V (S.C.E.) was transformed into a sharp peak on addition of chlorides ; the peak at first increased with increasing chloride concentration, to decline again at still higher chloride concentrations. The addition of serum albumin had the same effect on the predissolution wave as had complexing ions : the wave increased in height and its peak shifted to more positive potentials. Based on this finding, an analytical procedure was worked out permitting the estimation of serum protein in a concentration range fromn 2 to 200 μg/ml. Anodic a.c. polarography is a most sensitive method for the early detection of growing microorganisms, especially moulds, contaminating distilled water.
