Precipitation Diagrams of Struvite and Dissolution Kinetics of Different Struvite Morphologies [PDF]
Croatica chemica acta, 2002 Spontaneous precipitation in the systems MgCl2-H3PO4-NH4OH-0.15 mol dm-3 NaCl-H2O, MgSO4-NH4H2PO4-H2O and MgSO4-NH4H2PO4-0.15 mol dm-3 NaCl-H2O was studied at 25 °C and 37°C and initial pH = 4. Precipitates aged for 24 hours and 30 days were characterized by means of chemical analyses, X-ray diffractometry, FT-IR spectroscopy and thermogravimetry ...

Total Value of Phosphorus Recovery [PDF]
, 2016 Phosphorus (P) is a critical, geographically concentrated, nonrenewable resource necessary to support global food production. In excess (e.g., due to runoff or wastewater discharges), P is also a primary cause of eutrophication.

In Vitro Study on the Influence of Proline on Struvite Crystals
Hittite Journal of Science and Engineering, 2020 This study investigated the effect of amino acid proline, as crystal modifier, on the struvite crystallization in vitro conditions. The struvite crystals were evaluated experimentally through XRD, SEM, and FTIR to determine the structure, morphology, and

Effect of a struvite dissolution diet in cats with naturally occurring struvite urolithiasis [PDF]
Journal of Feline Medicine and Surgery, 2020 Objectives The aim of the study was to determine the efficacy of the low struvite relative supersaturation diet in dissolution of feline struvite cystoliths. Methods This was a prospective, open-label, two-center study. Twelve client-owned cats were enrolled based on the radiographic appearance of their uroliths and urinalysis parameters. Cats were fed
