Description
Abstract
Many organic compounds have been found to form stable complexes with certain metal ions. A complex may be defined as a compound in which the covalency of the element is greater than its valency, or those compounds of an element formed by means of co-ordinate links accepting or donating electrons (1).
In this study three organic compounds, diphenylthiourea, N-N dimethylparaphenylazoanaline, and 2,4 dlchlorophenoxyacetic acid were studied to determine the possibility for formation of solid precipitated complexes with the metal ions of cadmium, copper, cobalt, nickel, silver, and zinc* All possible combinations of the three organic compounds and the six metal ions were observed under two different pH conditions - acidic and neutral, Precipitates formed were analyzed quantitatively to determine the completeness of the precipitation of the metal and the structure of the complex formed. In this manner it was determined whether any of these three reagents, used under the stated conditions, could be utilized as analytical reagents for any of the six metals in qualitative and quantitative precipitations and separations.Many organic compounds have been found to form stable complexes with certain metal ions.
