Determination of a non-ionic surfactant 

I am interested in a method for determining the concentration of a non-ionic a surfactant in water. I am familiar with the CTAS method, but have heard of a spectroscopic method requiring no sample preparation in the mid to high 200 nm range. Are you familiar with such a method?

Sorry, don't know. But for the purpose of completeness, (and so I didn't completely waste my time looking up the method), I herewith post the reference for the CTAS method, Standard Methods for the Examination of Water and Wastewater, 1985, 16th Edition, Method 512 C. Nonionic Surfactants as CTAS. (Cobalt thiocyanate active substances)
