Effect of ionic strength on aggregation of nile red and coumarin 30 in aqueous medium: primary kinetic salt effect or salting-out effect?
Nitin Chattopadhyay, Arindam Das
Abstract
, our experimental results do not show any differential effect, in terms of making the aggregation process faster, and hence rule out any effect of Hofmeister series on the self-aggregation process. The detailed study explicitly establishes that it is the 'primary kinetic salt effect' and not the 'salting-out effect' that is involved in the present case.
