英文摘要 | A simple spectrophotometric method applicable to waste water bodies is developed for the determination of anionic surfactant (AS). An ion- association complex is formed between an anionic surfactant Sodium dodecyl sulphate (SDS) and a cationic dye Crystal Violet (CV).The absorbance of the complex in benzene layer is measured spectrophotometrically at maximum wave length (גּ max) of 565 nm. Under the optimal experimental conditions, absorbance of the organic extractant obeyed Beer’s law over the range of 0.75-10.00 µg mL-1 of SDS and the LOD was 0.01312 µg L-1. |
