“…VANS & Fishburn (1943) have suggested that the first stage of dis-E infection by water soluble bactericides was an adsorption to the surface of the bacteria, followed by a chemical reaction between the adsorbed bactericide and the active proteins of the bacteria. Knaysi & Gordon (1930) were able to show that iodine was adsorbed by yeast from an aqueous iodine and iodide solution according to the Freundlich isotherm, whilst Habs (1932) undertook an investigation of the binding of iodine by bacterial cultures, from which he postulated the existence of an adsorption process involving an irreversible and a loose binding by the bacteria. Aqueous iodine and cetomacrogol systems do not produce the characteristic blue colour with starch, itself an adsorption phenomenon, and do not usually stain fabrics, in contrast to solutions of iodine and potassium iodide in ethanol.…”

The uptake of iodine by baker's yeast, serum, E. coli and Staph. aureus from aqueous dilutions of an iodine non‐ionic surface‐active agent complex was compared with that from aqueous dilutions of an ethanol and potassium iodide solution. The form of adsorption isotherms depended upon the iodine system and the substrate. A characteristic of all isotherms was the high affinity at low iodine concentrations. Except where high ethanol concentrations remained, uptake was greater from the ethanol: potassium iodide dilutions. The pH of the iodine system also influenced the uptake, the effect varying with the iodine system and the substrate.
