Spectrophotometric investigation of vanadium(4) complexing with monoamine complexones
Description
Interaction of vanadium(4) with iminodiacetic (H2Ida) and methyliminodiacetic (H2Mida) acids by μ = 0.1 (NaClO4) and t = 20±2 deg C is studied through the spectrophotometric method. It is established that the process of complex formation in quasi-binary systems due to competitive effect of hydroxide ions depends to a large degree on the ligands concentration and properties. The VOIda, VO(OH)Ida-, VOMida, VO(OH)Mida- complexes are identified. The stability constants logarithms of these complexes are equal correspondingly to 9.81±0.02, 18.19±0.03, 10.15±0.03, 18.34±0.02. The results of the study on the VO2+-HIda and VO2+-H2Mida systems agree well with the regularities, identified by the study on the vanadium(4) complex formation with other complexones of the iminodiacetate series
