Determination of Micro Aluminium by Fluorescene Quenching Method with p—Fluoropheny Ifluorone in the Presence of Cetyhrimethy Ammonium Bromide |
| |
| Abstract: | Based on the fluorometric guenching effect of p—FPF—CTMAB due to the formation ofAI (Ⅲ)—P—FPF—CTMAB complex.A new method with the detection limit of 2.6 ppb has beendeveloped for the determination of micro AI (Ⅲ).The maximum fluorometric wavelength of P—FPF—CTMAB is 551 nm.This method can be used for the determination of micro AI (Ⅲ) in (?)apwater. |
