摘要: Abstract The effect of tartrates with various counterions on the crystallization CaOxa in vesicles was investigated concentration range from 0.3 to 66.7 mM lecithin vesicle solutions using X-ray diffraction (XRD) and Fourier transform infrared (FT-IR) spectroscopy. Various hydrogen, sodium, potassium, a mixture sodium potassium cations were considered. For K2tart NaKtart, only calcium oxalate monohydrate (COM) trihydrate (COT) obtained depending concentrations. However, for H2tart Na2tart, dihydrate (COD) first induced debt COM, then COT COM COD. maximum percentages COD about 55% 35% Na2tart ranges 6.7 13.3 1.67 10 mM, respectively. Linear relationships between decrease mole percent (mol%) crystals, or increase mol% crystals logarithm molar tartrates. different results are discussed terms reduction degree freedom associated adsorption process at membrane–water interface, ionic radii counterions, solubility molecular structures hydrates, hydrates.
