Adsorption and Precipitation of Tetracycline with Struvite
Water Environment Research, 2007The interaction of tetracycline with struvite during adsorption and precipitation processes was investigated. Tetracycline removal by adsorption was affected by solution pH, contact time, and struvite concentration. The lowest tetracycline removal (8.4%) was observed at pH 7.7, the dissociation constant (pKa2) of tetracycline.

The solubility of magnesium-ammonium-phosphate (struvite) has been studied employing radioisotope32P as tracer. The amount of sample in solution is determined by measuring the Cherenkov radiation due to the fast β-particles emitted from this radionuclide. The themodynamic solubility product is determined at various temperatures and compared with former

A SOLUBILITY AND THERMODYNAMIC STUDY OF STRUVITE
Environmental Technology, 2007Accumulation of magnesium ammonium phosphate hexahydrate (struvite) on surfaces in contact with wastewater, especially in anaerobic sludge digestion and post-digestion processes, is a widely reported problem in the wastewater treatment industry. The solubility and thermodynamic properties of struvite at different temperatures was studied.

Dissolution of a Struvite Nephrolith in a Dog
Journal of the American Veterinary Medical Association, 1979SUMMARY A large radiodense calculus in the left renal pelvis of a 22-month-old, male Great Dane disappeared one month following surgical removal of two struvite (magnesium ammonium phosphate) calculi from the right renal pelvis. The dog's urine likely became undersaturated with struvite for a sufficient period to permit dissolution of the renal ...

The origin and causes of struvite stones
International Urology and Nephrology, 1991The aim of this paper is to evaluate the possible causes of the origin of "infection stones". The main differences between the ordinary biochemical parameters of a group of patients with this type of stones was analyzed and compared with a group of oxalocalcic stone-formers and with a group of healthy subjects.

Etiopathogenesis of Canine Struvite Urolithiasis
Veterinary Clinics of North America: Small Animal Practice, 1986Urine must be oversaturated with magnesium ammonium phosphate for struvite uroliths to form. Oversaturation of urine with magnesium ammonium phosphate may be associated with several factors, including urinary tract infections with urease-producing microbes, alkaline urine, diet, and genetic predisposition.

Seminars in nephrology, 1997
Although calcium oxalate stones are the most common type of calculi found in the United States, struvite or infection stones are quite common and generally pose a difficult treatment dilemma. The presence of urinary infection with a urease-producing organism is necessary for these stones to form.

TREATMENT OPTIONS IN STRUVITE STONES
Urologic Clinics of North America, 1997Urinary calculi have plagued man over the centuries. The epidemiology and pathogenesis of infection have been studied. The curative treatment remains problematic. Without therapy, a vicious cycle of stone formation occurs. This results in renal damage and even death. Multimodality therapy is the key.

Struvite urolithiasis in a B6C3F1 mouse
Laboratory Animals, 1992In a 2 year carcinogenicity bioassay using B6C3F1 mice, one male mouse developed clinical signs near termination of the study, comprising skin sores around the prepuce, penile prolapse and urine scalding. The predominant finding at necropsy was a markedly distended urinary bladder filled with numerous crystallized particles. Microscopically, there was

Frankfurt a.M. Phosphor ist ein wichtiger Pflanzennährstoff und somit unverzichtbar für die Nahrungsmittelproduktion. Die derzeitigen Phosphorquellen sind jedoch endlich. Im Projekt „P-Net“ bewertet das Julius-Kühn-Institut (JKI) die Wirksamkeit des P-Recyclingdüngers Struvit.
