Abstract: This study attempts to synthesize a new reagent for spectrophotometric use with the view of joining the ongoing research efforts in the world on highly sensitive chromogen for the detection of harmful metal ion in solution. This reagent: Dioxallic Dithiophenyl Azomethine Hydrazine (DDAH) was synthesized following the reaction pathway of Carbonyl compounds especially aldehydes in general with primary base, to form condensation products of the type RCH=NR¹. The reaction was brought about by heating a mixture of 0.02mole of dioxallic dihydrazide (dissolved in ethanol) to 0.05 mole of 2-thiophene carboxaldehyde and the reacting mixture was refluxed for 7 hours. The solid product, separated on cooling, was filtered and re-crystallized from aqueous alcohol. The optimum reaction conditions of the reagent have been established with three (3) metals namely: chromium (VI), iron (II), iron (III), nickel (II), cobalt (II), zinc (II), mercury (II), cupper (II), vanadium (V), and lead (II). The impact of micelles on the spectrophotometric relevance of the reagent was carried by using both n-Hexadecyl Trimethyl Ammonium Bromide (HTAB) and Sodium Dodecyl Sulphate (SDS). The results emanating from the analytical parameters clearly show the variations in maximum absorbance and absorbance in all the 3-metals used for the study. The study thus concludes that there exists some spectrophotometric relevance in the new reagent.
