| Abstract: | A simple and rapid spectrophotometric method
for the determination of sodium dodecyl sulphate (SDS), an anionic surfactant
(AS) is developed. SDS forms a yellow coloured complex with acridine orange (ACO),
a cationic dye. The complex is extracted in toluene. The absorbance of the
complex in toluene layer is measured at maximum wavelength (λmax) of
467 nm. The calibration curve is linear in the range of 0 – 6.0 ppm of SDS
concentration. The method is compared with the
standard MBAS method in terms of time, ease and accuracy. It is noticed that
the present method is much easier and less time consuming. The method requires
chemicals, which are less toxic than those required for the standard method.
The method is applicable to wastewater analysis. |
