Spectroscopic and Microscopic Identification of the Reaction Products and Intermediates During the Struvite (MgNH4PO4·6H2O) Formation from Magnesium Oxide (MgO) and Magnesium Carbonate (MgCO3) Microparticles

A new article published on using sustainable and abundant magnesium sources in the form of MgO and MgCO3 to recover nitrogen and phosphorus from wastewater to produce sustainable fertilizers. In collaboration with University Wisconsin Oshkosh Prof. Jennifer Schuttlefield-Christus. This manuscript is addressing nitrogen management challenges and utilizes solid oxide and carbonate minerals rather than expensive water soluble magnesium salts.

Manuscript on properties of aqueous urea phosphate solutions published

Two Lehigh undergraduates, Criztel Navizaga and Jennifer Boecker, led the effort to evaluate phase and spectroscopic properties of urea phosphate solutions for sustainable nitrogen management. Nitrogen management is one of the 14 National Academy of Engineering challenges and we are addressing it by synthesizing urea fertilizers in the form of molecular adducts with inorganic acids. For the first time Raman spectroscopy revealed that even in aqueous solutions urea is coordinated to acid molecules.
