Solubility Study and purification Of Industrial triple superphosphate in aqueous solution
Journal Title: JOURNAL OF ADVANCES IN CHEMISTRY - Year 2014, Vol 9, Issue 2
Abstract
Triple Superphosphate (TSP) is a chemical fertilizer, acknowledged by its important content of phosphorus, necessary element for plants. It’s obtained by adding phosphoric acid to phosphate ore, consisting of calcium phosphate containing many impurities. TSP was dissolved at different temperatures and in various amounts of water, filtered to remove insoluble compounds. Then the ionic conductivity was monitored for each solution as a function of the added amount of TSP. Aqueous solutions were evaporated to dryness and analyzed the P2O5. The starting materials and final products were analyzed by several methods (XRD, IR, NMR, SEM) confirming that after dissolution the product was purified.

Myths and verities in protein folding theories Part I: Anfinsen hypothesis and the search for the global minimum in the Gibbs energy landscape
Anfinsen’s thermodynamic hypothesis may be interpreted in two ways: One, that the native 3D structure of the protein, resides in the absolute minimum in the Gibbs energy landscape (GEL). The second, that the Gibbs ener...
