Application of Simms Constants in Modeling the Titrimetric Analyses of Fulvic Acids and Their Complexes with Metal Ions

Dynamic buffer capacity versus alkalinity. Formulation in terms of Simms constants idea

“…The A value (Eq. 8) is termed as alkalinity, perceived here as a simple case of total alkalinity, TAL [12][13][14][15]. Then from Eq.…”

“…The Simms constants idea was extended [3,4], on modeling of acid-base titration realized according to isomolar mode [5][6][7][8][9][10][11]. Its further extension concerned the systems where total alkalinity (TAL) was modelled [12,13], also in the systems with fulvic acids [14]. This idea can be extended on biological systems, such as the lymphatic system in living organisms.…”

“…C0 mol/L; the gi are ascribed to these acids as (virtual) dissociation l h l b d constants values. The relations between gi and Ki values were formulated [14].…”

Principles of Titrimetric Analyses According to Generalized Approach to Electrolytic Systems (GATES)

“…[29] was referred to complex acid-base equilibria related to nonstoichiometric species involved with fulvic acids and their complexes with other metal ions and simpler species present in natural waters. For mathematical description of such systems, the idea of Simms constants was recalled from earlier issues e.g., Refs.…”

“…The detailed considerations in this chapter are based on principles of the generalized approach to electrolytic systems (GATES), formulated by Michałowski [9] and presented recently in a series of papers, related to redox [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] and nonredox systems [27][28][29][30][31][32] in aqueous and in mixed-solvent media [33][34][35][36][37]. The closed system separated from its environment by diathermal walls secure a heat exchange between the system and its environment, and realize dynamic processes in a quasistatic manner under isothermal conditions.…”
