-4.5.1.1
Sodium salt of fluorescein.
To 10 ml. of a 1N.
sodium hydroxide
solution add 1500 mg. of the sample and
dilute the sample solution to 1000 ml. with distilled water-
Transfer a 50 ml. aliquot of the solution to another 10 ml. of
1N sodium hydroxide solution and. dilute to 100 ml. volume
with distilled water.
Take a 20 ml.
aliquot of this solution,
add to 10 ml.
of 1N sodium hydroxide
solution and dilute to
1000 ml.
with distilled water.
The final solution contains
1.5 mg.
of sample.
Using reagent grade fluorescein, prepare two standard
solutions containing
1.0 and 1.5 mg/1 of fluorescein,
respectively,
in accordance with the procedure described above
for the sample.
Determine
the absorbance of the two standard
solutions using an appropriate spectrophotomete r set at 490
nm.
Plot the absorbance values
VS
.
the
respective
concentrations and draw
a straight line
through the two points
to obtain a calibration curve.
The straight line should go
through the origin of the x ,y axis.
