Abstract

The coordination compound of gallium (III) with stillbazo-stillbene-4,4'-bis [(1-azo)3,4-dihydroxybenzene]-2,2'-disulfonic acid has been investigated by spectrophotometric method in the presence of cetyl pyridinium chloride (CPC) as surface active compound. It has been determined that the mixed ligand complexes were formed with the ratio of 1:2:4 in CPC-mediated phase. The molar coefficient and the stability constant of the complex compound βк = 6.8 × 109, eк = 66,834 have been studied by various spectrophotometric methods. The effect of pH, time, temperature, concentration of the reagents and CPC on formation of the unmixed and mixed ligand coordination compounds has been also studied. It has been determined that the Beer’s law is respected within 0.008 - 10 μg of Ga(III) in 25 mL solution. The technique of the photometric determination of gallium in natural compositive objects and industrial objects has been developed.

Highlights

The azoderivatives of pyrocatechin as analytical reagent have been studing in different research works [1] [2] [3]

Summary

Introduction

The azoderivatives of pyrocatechin as analytical reagent have been studing in different research works [1] [2] [3]. A lot of works devoted to studying of nitropyrocatechin as analytical reagent for spectrophotometric determination of Al, Ga, Ge [4]. Under the influence of surface-active compound (SAC), in metal-dryed organic reagent-SAC systems the great bathochromic shift and hyperchromic effect were observed within spectra of adsorption band of complexes [9]. One of the disadvantages of these reagents is that the formed complexes are sparingly soluble This drawback can be eliminated by using of modifying additives, especially SAC, which can improve the chemical and analytical characteristics of these reagents
