SULFO SALICYLIC ACID

I'm looking for an analysis that will give me the concentration of SULFO SALICYLIC ACID, if possible by titration. I have hat problems finding an analysis elsewhere, and we would like to have at better fix on the concentration in our baths.

Anne,

5ssa can be titrated photometrically by ferric chloride ⇦ this on eBay or Amazon [affil links] . To start first try to create calibration curve by concentration and dilution of 5SSA from .5 to 3 mg/l by .5 mg increment. using 3% Cl3Fe in buffered 6-7 ph .
