چکیده انگلیسی
The complex species formed between vanadium(III)-salicylic acid (H2sal) and the small blood serum bioligands: lactic (Hlac), oxalic (H2ox), citric (H3cit) and phosphoric (H3PO4) acids in aqueous solution were studied by means of electromotive force measurements emf (H) at 25 °C and 3.0 mol·dmâ 3 KCl as ionic medium. Data analysis using the least-squares program LETAGROP taking into account the hydrolytic products of vanadium(III) and the formed binaries complexes indicated the formation of V(sal)(lac) complexes, [V(sal)(lac)(OH)]â and [V(sal)(lac)(OH)2]2 â in the vanadium(III)-H2sal-Hlac system. Species V(sal)(Hox)+, [V(sal)(ox)]â were also detected. [V(sal)(ox)(OH)]2 â, [V(sal)2(ox)]3 â and [V(sal)(ox)2]3 â were observed in the vanadium(III)-H2sal-H2ox system; the complexes V(sal)(H2cit), [V(sal)(Hcit)]â, [V(sal)(cit)]2 â and [V(sal)(cit)(OH)]3 â in the vanadium(III)-H2sal-H3cit system and the species V(sal)(H2PO4), [V(sal)(HPO4)]â and [V(sal)(PO4)]2 â were detected in the vanadium(III)-H2sal-H3PO4 system. The corresponding stability constants were estimated.
