Preferred Abstract (Original): 

A sensitive method for the determination of trace amounts of mercury by complexation with 3-(2-Thiazolylazo)-2, 6-diaminopyridine (2, 6-TADAP) is described. Hg(II) forms a 1:2 complex with the reagent. Beer's law is obeyed over the range 5-40 μg in the total volume of 10 ml. The molar absorptivity was found to be 1.4 times104 L mol-1 cm-1. This method is simple, rapid and involves no extraction steps whereby the use of gelatine as a solubilizing agent is described.
