We manufacture Iodophors and currently purchase Hydriodic Acid and cude iodine in the process. We're looking to produce Sodium Iodide to replace the use and expense of Hydriodic Acid. Would you be interested in acting as a consultant in this project?

Thanks for the reply, maybe we aren't using the sequence. We are using formic acid as the reducing agent, putting the formic in after the reaction, however when it drops the pH, we get the iodine color in the solution. Can you recommend a procedure?? Thanks, Johnd

We are trying to make Sodium Iodide 57% solution using NaOH 50% and crude Iodine. We finish with a pH of the solution of approx 12, when we try to drop the pH to approx 8.5-9, the solution becomes deeply colored. Can someone help with what we are doing wrong?? Thank Johnd
