dc.description.abstract The many questions raised by gallstone disease on the absorption of water of different compositions have led us to study their effect on the development of calcium oxalate stones. As the amount of water is important, the composition is also an essential parameter for the healthy spa guests. In this perspective we became interested in studying the influence of some water on the artificial calcium oxalate crystallization and the influence of mixing pairs of studied components on the crystallization of calcium oxalate. Perform the experiments was made at 37 ° C for final concentrations of solutions of calcium chloride CaCl2 and sodium oxalate C2O4Na2 in the test were 4 and 1 mmol L-1. The ionic strength was 0.15 M. The substances studied were calcium ions between 5 and 150 mg.L-1, magnesium ions between 5 and 100 mg.L-1, sodium ions between 5 and 100 mg.L-1, potassium ions between 1 and 7 mg.L-1, fluoride between 1 and 3 mg.L-1, sulfate between 20 and 220 mg.L-1, bicarbonate between 50 and 1200 mg.L-1 and nitrate between 5 and 50 mg. L-1. The polarizing light microscopic analysis was used with photographs taken to observe the effect of the inhibitor on the facies of the crystals. The experiments were performed at the base of a planning matrix which will reduce the number of tests to be performed. Excel and Statistica software was used for the treatment of data collected. en_US
