Abstract
Solochrome Black T reagent product a violet complex with Holmium(III)in aqueous solution media at (pH=5).The complex was found to be stable at the given pH.Beer,s law is obeyed in the concentration range(6.06x10-7-54.56x10-7M) with molar absorptivity of (14432L.mole-1.cm-1).The stoichometry of complex was confirmed by using mole ratio method which indicated the ratio of reagent to metal is 2:1.The effect of the presence of different cations and anions as interference in the determination of Holmium (III) under the given condition were investigated .The proposal method was applied for the determination of Holmium in standard rock sample by direct methods and a satisfactory results were obtained.
