The salt addition inhibits excited state proton transfer in the fluorescent probe bound to micelles.
- class="label">•
The observed salt effect is due to anion accumulation near the nonionic particle surface.

The thiocyanate ions exhibit much stronger effect than chlorides.

The anion effect is due to a synergism between the ion polarizability and hydrophobicity.
