摘要: The dependence of L-glutamine protonation and its complexation with dioxovanadium(V) on ionic strength (I) is reported in sodium perchlorate solution as a background salt. measurements have been performed at 25 ± 0.1°C various strengths the range 0.1 to 1.0 mol/l, using combination potentiometric spectrophotometric techniques. overall analysis present previous data dealing determination stability constants different allowed us obtain general equation, by which formation constant determined fixed can be calculated, good approximation, another strength, if ≤ I≤ mol/l (NaClO4).
