The thermodn. of the interaction of L-glutamic-N,N-diacetic acid (GLDA) with protons was studied potentiometrically at different temperatures, ionic strengths and ionic media. Four protonation constants and corresponding enthalpy changes occurred at infinite dilution together with temperature and ionic strength coefficients The medium effect was also interpreted in terms of the formation of weak complexes between the ligand and the cations of supporting electrolytes, resulting in a greater tendency of GLDA to chem. interact with Na+ rather than K+ and, in turn, (CH3)4N+. Formation constants of GLDA with Cd2+ were determined in NaCl(aq) at different ionic strength values. Five complex species were found, namely CdL2-, CdHL–, Cd2L0(aq), Cd2L0(aq), and Cd(OH)L3-, whose formation constant values at infinite dilution were log β = 12.68, 17.61, 20.76, 17.52, and 1.77, resp. All the species results were relevant in the pH range of natural waters, although the Cd2L0(aq) was observed only for CCd ≥ CGLDA and concentrations of >0.1 mmol dm-3. The sequestering ability of GLDA toward Cd2+, evaluated by means of pL0.5, was maximum at pH 10, whereas the presence of a chloride containing a supporting electrolyte exerted a neg. effect. Among new generation biodegradable ligands, GLDA was the most efficient in Cd2+ sequestration. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Related Products of 75-57-0).
Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).Related Products of 75-57-0
