3.5. Effect of ultrasonication and centrifuge time
As is known,analytical application of ultrasonic radiation has
an important role in increasing the kinetics and performance of
extraction by increasing the interactions between analyte and
extraction solution for mass transfer [32,33]. Hence,after addition
of the extraction solvent(1-decanol–THF) in sample solutions,
the sample solutions were placed in ultrasonic water bath.
The supramolecular solvent,made up of reverse micelles of 1-decanol dispersed in THF:water formed. Linear increase in recovery was obtained as ultrasonication time was increased up
to 5 min. which was enough for maximum recovery. Hence,
5.0 min. of ultrasonicaiton time was used for further work.
