Treatment of Tunisian salt lakes using solubility phase diagrams

Investigations into tie lines and solubility curves on phase diagrams in open-tubular capillary chromatography using ternary mixed-carrier solvents.

Open-tubular capillary chromatography using a ternary solvent mixture consisting of a water-hydrophilic-hydrophobic organic solvent as a carrier solution has been developed. When the ternary carrier solution is fed into the capillary tube, the carrier solvents are radially distributed and generate inner and outer phases in the tube. The outer phase functions as a pseudo-stationary phase in ch...

Geochemical Phase Diagrams and Gale Diagrams

The problem of predicting the possible topologies of a geochemical phase diagram, based on the chemical formula of the phases involved, is shown to be intimately connected with and aided by well-studied notions in discrete geometry: Gale diagrams, triangulations, secondary fans, and oriented matroids.

The influence of fluoride on the solubility of bone salt.

The decrease in the incidence of dental caries which follows the addition of fluoride to municipal water supplies has been attributed to the inhibition of enzyme reactions and of bacterial growth (2-4), and to a decrease in the solubility of bone salt. Evidence that fluoride decreases the solubility of bone salt consists of many reports which show, principally, that (a) a smaller amout of ename...
