use 250-300 range in your UV spectroscopy. You can get a peak at 275+_5nm. Prepare sample in hexane, methanol, etc

Decai Jin

Using GC-MS is better than UV.

Dione Morita

Unfortunately, you can't accurately determine the concentrations of phthalates by UV spectroscopy in complex mixtures. Use GC-MS or HPLC-MS.
