| 英文摘要 | Spectrophotometric determination of trace anionic surfactants such as SDS and SDBS in water samples based on a simple and rapid preconcentration technique of collection on an organic solvent-soluble membrane filter, has been proposed. The anionic surfactants are collected on a nitrocellulose membrane filter as an ion-associate complex with the cationic complex of iron (II)-3-(2-pyridyl)-5,6-diphenyl-1,2,4-triazine (pyridyl diphenyltriazine, PDT). The membrane filter with the analyte is dissolved in a small volume of organic solvent, and the absorbance of the resulting solution is measured against a reagent blank. The maximum absorption is at 555 nm and the apparent molar absorptivities are 8.93x10(3) 1 mol(-1) cm(-1) for SDS and 8.51x10(3)1 mol(-1) cm(-1) for SDBS. Beer's law is obeyed over the range of 10-100 mu g for SDS and SDBS and the detection limit is 0.0043 mg 1(-1) for SDS and 0.0052 mg 1(-1) for SDBS, respectively on a 3 a basis. Interference from Cu2+ and Ni2+ can be eliminated by masking. |
