Systematic analysis of iodine extraction technologies from highly mineralized waters including concomitant waters of oilfields were done. It is proved that the estimation of the oxidation-reduction equilibrium in iodine extraction technological systems by the value of Eh can be conducted only at identical values of pH. At each stage of the technological process optimal parameters (pH, Eh, rH 2) were determined through a potentiometric method of analysis. Research results are: significant reduction in sulfuric acid consumption; reduction in toxic wastes formation; reduction in sulfate contamination of the final product. The high iodine extraction effect in crystal form is achieved by exclusion of side processes. Results are implemented in research-industrial equipment for iodine extraction from underground highly mineralized water. The mass fraction of iodine in the final product is 99,4-99,6%.
