14 Calcium carbonate is a popular phosphate binder because of both its availability over the counter and its low cost relative to other phosphate binders. Not only does it bind dietary phosphate when given with meals, but some believe it has the added advantage of preventing or reversing ...
Identification test1 g of the sample was shaken with 20 ml of water, and the acetic acid test solution (TS-1) was added to dissolve the sample. The calcium test (IT-10) of this solution was positive. ToxicityADI is not subject to restrictive regulations (FAO/WHO, 2001). ...
(A1−A2)/2). A1was fixed at 1, and A2, p and t1/2were obtained from fitting the data to equation 1. CHT was used as a measure of inhibition potentials of the peptides. A one-way ANOVA in combination with Tukey post hoc test at p<0.05 level was used to probe statistical ...
Two hundred milliliters of 15 mM (CH3COO)2Ca aqueous solution was added to the same volume of 9 mM (NH4)2HPO4 aqueous solution to set the Ca/P molar ratio to 1.67; the mixture was stirred for 5 min at 20 °C. The solution temperature was increased to 60 ...
In this study, calcium and magnesium were removed from Tunisian dam, lake, and tap water using Donnan Dialysis (DD) according to the Doehlert design. Three cation-exchange membranes (CMV, CMX, and CMS) were used in a preliminary investigation to establish the upper and lower bounds of each...
Equation (1) was used to determine the percentage of inorganic solutes and biomolecules removed from the corn stream, whereas Equation (2) was used to calculate the adsorption capacity qe (mg/g) of calcium alginate-based biopolymers [31]: Cremoved(%) = C0 − CtC0·100Cremoved(%) = ...
Calcium is produced industrially by two methods: (1) by heating a briquetted mixture of CaO and powdered aluminum at 1200°C in a vacuum of 0.01-0.02 mm Hg; the calcium vapors, evolved according to the equation 6CaO + 2A1 = 3CaO ⋅ A12O3 + 3Ca, condense on a cold surface; (2...
