	abstract = {One of the key global challenges forthcoming will be maintaining a clean, useable natural water supply.  Anthropogenic wastewater is an unavoidable result of population growth and societal development; therefore the treatment of wastewater is of the utmost importance.  The mineral struvite (magnesium ammonium phosphate hexahydrate, MgNH4PO4{\textperiodcentered}6H2O) is a cryst. material that occurs naturally in decompg. org. materials and been obsd. in sludge derived from the anaerobic digestion of animal farming liq. wastes and treated wastewater sludge.  The accumulation of struvite on pipe walls and equipment surfaces has plagued the wastewater treatment industry though the formation of struvite prior to the treatment process could potentially provide a pathway for the sustainable recovery of the major nutrients nitrogen (N) and phosphorus (P).  Current methods of nutrient removal from wastewater are mostly based on insol. Fe, Al and Ca salt formation followed by landfill disposal without returning them to the environment.  Struvite is one of the most promising chem. platforms for recovering nutrients, which previously was done using expensive water-sol. magnesium salts.  Our objectives were to examine the potential of low soly., naturally abundant magnesium inorg. materials (MgO and MgCO3) for the utilization of nutrient recovery from wastewater via time resolved ex situ XRD, ATR-FTIR and Raman analyses, and SEM measurements to identify reactive intermediates and use spectroscopic data for kinetics anal.  Our data suggest that a common reactive intermediate between homo- and heterogeneously nucleated struvite exists that is due to the amorphous magnesium hydroxide structural units.  The presence of low coordination O4C-H, O3C-H and O1C-H surface hydroxyl groups, assocd. with the surface steps, edges and kinks is proposed to enhance struvite formation and increase in their abundance and stabilization are suggested for the MgO and MgCO3 prepn. before the struvite recovery.  Two different crystal morphologies (needle and rhomboidal) were obsd. for reactions with 600 and 4000 ppm of (NH4)2HPO4, which were proposed to form due to the kinetic control of the reaction at higher concns.  Finally, Raman spectroscopy was used to measure the relative kinetics of struvite formation utilizing the relative populations of the magnesium carbonate or struvite, as obtained from the area under the 1125 and 950 cm-1 peaks providing a spectroscopic method to monitor reactive solid magnesium source conversion into struvite.

	abstract = {Design and use of the adjustable N:P2O5 ratio fertilizers is crucial in proper nutrient management if sustainable phosphorus use is to be ensured.  Overfertilization with phosphorus can lead to its fixation in soil, as well as the unwanted environmental phenomena, such as eutrophication.  Urea phosphate, CO(NH2)2{\textperiodcentered}H3PO4, based liq. fertilizers were synthesized in this work, and their resulting physicochem. properties were detd.  For this purpose, phase compn. information on the CO(NH2)2{\textperiodcentered}H3PO4-CO(NH2)2-H2O ternary system was analyzed, and crit. points on the polytherm were detd.  Liq. fertilizer compns. were detd. and their corresponding physicochem. properties established.  Raman spectroscopy showed that CO(NH2)2{\textperiodcentered}H3PO4 partially retains its strong bonding interactions between both mol. adducts in aq. solns. suggesting their improved nitrogen management efficiency in soils.  Effect of these acidic pH fertilizer solns. on the pH of soil was detd. and was found negligible.  The potential of these fertilizers for reducing the loss of nitrogen from the wet soil is also discussed. [on SciFinder(R)]},

	abstract = {Zinc contg. org. materials were synthesized using dairy wastewater and solid zinc waste derived from zinc nitrate with the goal of obtaining biodegradable, slow release, micronutrient contg. fertilizers.  The developed synthesis procedure involved heating at mild 55 {\textdegree}C temp., followed by pH adjustment to 7, pptn., and drying.  The resulting solid materials were characterized using wt. anal., thermogravimetric anal. (TGA), X-ray diffraction (XRD), and Fourier transformed IR spectroscopy (FTIR).  Higher wastewater-to-zinc nitrate ratios of 1:1/5 yielded amorphous materials with no inorg. zinc compds. detected.  TGA anal. showed very complex thermal behavior due to the large amt. of orgs. present while FTIR anal. suggested the presence of both coordinated and uncoordinated carboxylic acid and ester groups.  The developed process can have a variety of applications in recovering Zn from waste sources, such as tire crumb, while returning this valuable micronutrient into soil as a slow release biodegradable fertilizer.
