Once it gets into an aqueous mobile phase, any salt will dissociate. Therefore, as far as HPLC is concerned, the potassium salt of phenol = phenol.

Similar to a question asked of me Wednesday: how much was salicylic acid, and how much was sodium salicylate. Use some acid in your aqueous portion of the mobile phase, along with methanol or ACN, RP-18, and UV detection.
