Thermodynamics of Stability Constant of Binary Complex of Nicotinamide with Mn++
摘要:
The stability constants of the binary complexes of Mn2+ with nicotinamide (NA) were determined from potentiometric pH titrations data at 15.0, 25.0 and 35.0℃ and I=0.1,0.2,0.4 mol L-1 (NaClO4). The formation of binary 1:1, 1:2 NA-Mn complexes at three different temperatures and the influence of three different ionic strength on their stability were reported. The thermodynamic parameters (△Gfo, △Sfo, △Hfo) for the complex formation reaction were estimated from stability constant at different temperatures.
