【Abstract】 The micellar colour reaction of silver(Ⅰ) with meso tetra(3 chloro 4 hydroxy 5 methyoxyphenyl)porphyrin (T(3Cl 4H 5MOP)P) Tween 80 TDS and the optimal formation condition of the complex have been studied.In the base medium at pH11.60 buffer solution of borax and in the presece of Tween 80 TDS,Ag(Ⅰ) reacts with T(3Cl 4H 5MOP)P to form a 1∶1 micellar complexes.The maximum absorption wavelength and the apparent molar adsorptivity of the complex are 432nm and 2.25×10 5 L·mol -1 ·cm -1 ,respectively.Beer’s law is obeyed in the range of 0～7.25 g Ag(Ⅰ)/25ml.The method has been successfully applied to direct determination of trace Ag(Ⅰ) in the photographic paper and waste water of fixing bath with satisfactory results.更多还原
