Effect of Triton X-100 concentration
Optimization of this factor was carried out in order to use a
minimum surfactant concentration with maximum extraction efficiency.
The effect of Triton X-100 concentration on the absorbance
of carmine dye was studied in the range of 2–10% w/v. The results
in Fig. 2 indicate the absorbance of extracted carmine increases up
to 8% w/v and then remains constant. In order to obtain the highest
pre-concentration 8% w/v was used as the appropriate concentration
in this work.
