We know salicylic acid powder is insoluble in water. Literature say that they added salicylic acid solution to the water based slurry to detect the *OH radicals, which are generated due to Fenton reaction in the slurry. I have purchased salicylic acid powder from Sigma Aldrich. But I do not know how to dissolve it in the water based slurry. Because literature dose not say the details. They do not make the issue clear. I am seeking help from the experts.

Hydroxyl radicals attack the aromatic ring system of the acid. This would change the absorption frequency and make the compound more hydrophilic. Else you can use NMR or MS to determine derivatives (eg. Article Determination of hydroxyl radicals using salicylate as a tra...
).As for the solvation issue consider using a detergent like Triton-X or Tween-20. That is assuming you cannot dissolve in ethanol and then dilute into the aqueous slurry.
