The influences of activity of calcium and oxalate ions, monovalent electrolytes, sulfate, phosphate, pyrophosphate, and citrate ions on the electrophoretic mobility.

During the course of studying the electrokinetic behavior of calcium oxalate monohydrate (CaC'H20), it occurred to us that this material may have many of the characteristics that might favor the applicability of simple double layer models. This material is present in small amounts of human urine.

The electrophoretic behavior of calcium oxalate monohydrate was analyzed in terms of a simple double-layer model. The experimental results with a variety of electrolytes could be described nearly quantitatively with the Nernst-Gouy-Stern double-layer model Cited by: The stability of calcium oxalate is critical for the removal of sodium oxalate from sodium aluminate solutions.

This study investigated the behavior of calcium oxalate in sodium aluminate solution containing sodium by: 2. Abstract. Based on the structure of kidney stones, it is likely that they form as aggregations of preformed crystals, mostly calcium oxalate monohydrate (COM). In this study, we examined the ability of a macromolecular mixture isolated from the urine of normal individuals and stone formers to inhibit aggregation of preformed COM seed crystals in The electrokinetic behavior of calcium oxalate monohydrate in macromolecular solutions book by: T1 - Scanning electron microscopy of calcium oxalate crystal formation in experimental nephrolithiasis.

The solubility is less in neutral solutions containing moderate concentrations of ammonium oxalate owing to the common-ion effect hence a dilute solution of ammonium oxalate. The kinetics of crystallization of calcium oxalate mono- di- and trihydrates (COM, COD, and COT, respectively) has been studied in calcium oxalate supersaturated solutions, M in sodium.

The effects of these parameters on the mass spectra of calcium oxalate monohydrate, calcium carbonate and malonic acid were investigated in separate experiments. Influence of sample mass. Conditions.

Sample: Calcium oxalate monohydrate /5(35). Inspired by the observation that crystalline calcium carbonate and calcium phosphate biominerals frequently form via amorphous precursors, a wide range of studies have been performed which demonstrate that many inorganic crystals can precipitate from solution via amorphous phases.

This article considers the crystallization mechanism of calcium oxalate Cited by:   Calcium oxalate (CaC2O4) is a slightly solubleionic compound. Write the chemical equation that represents dissolving CaC2O4 in water: --I'm not sure if I've got this one exactly right. I think the equation of the ion-product expression of the saturated calcium oxalate.

The precipitate is soluble in acidic solution because the oxalate. The polymers that were prepared with dodecanthiol accelerated rather than inhibited calcium oxalate formation, implying a different mode of action on calcium oxalate crystallization.
