Solubility of Calcium Phosphate in Concentrated Dairy Effluent Brines

Measurement of pH in concentrated brines

Accurate measurement of pH in concentrated brines is a critical aspect of materials testing in the oil and gas industry. Concentrated sodium chloride solutions, typically up to 4 M and saturated with carbon dioxide, are often used to simulate production water during testing programmes. The pH of the solution may be adjusted to the desired value by the addition of sodium bicarbonate (to raise pH...

The Solubility of Tertiary Calcium Phosphate in Cerebrospinal Fluid

It was shown in a recent publication (1) that blood serum is normally supersaturated with tertiary calcium phosphate, and the suggestion was made that other body fluids are similarly supersaturated with this salt. In order to confirm this idea, solubility experiments were undertaken with cerebrospinal fluid; it was furthermore hoped that these studies might throw some light on the question of t...

The Influence of Proteins on the Solubility of Calcium Phosphate

Role of Amorphous Calcium Phosphate in Dentistry

  Objective: Amorphous calcium phosphate (ACP) is a reactive solution capable of releasing calcium and phosphate ions, conversion to apatite and remineralization of mineral tooth structure. This study reviews ACP structure, its properties and its applications in dentistry.   Methods: In this review study, keywords including “amorphous calcium phosphate”, “mineralization”, “hydroxyapatite”, “cas...

CALCIUM PHOSPHATE CEMENT: STUDY OF (BETA-TRICALCIUM PHOSPHATE, DICALCIUM PHOSPHATE AND CALCIUM CARBONATE SYSTEM

Calcium phosphate cements (CPCs), using B-tricalcium phosphate (ß-TCP, Ca3 (P04)2), dicalcium phosphate (DCP, CaHP04), calcium carbonate (Ca CO3), and hydroxylapatite (HAp, Ca10(P04)6(OH)2) as powder cement and disodium hydrogen phosphate (Na2HP04) solution as liquid component were prepared. After mixing the powder and liquid constituents, injectable and self-setting calcium phosphate cements (...
