Abstract Supported titanium dioxide‐based photocatalysts were investigated for the degradation of pharmaceuticals under irradiation with UV−A LEDs. Focus presented research was placed on kinetics different matrix influences and energy flux densities radiation. The chemical parameters, pH, orthophosphate, nitrogen concentration background organic investigated. results evaluated by time‐resolved ...

Effective manure management to efficiently utilize organic wastes without causing environmental degradation requires a clear understanding of the transformation of P forms from diet to manure. Thus, the objective of this study was to establish quantitative relationships between P forms in diets, feces, and manures collected from U.S. Northeastern and Mid-Atlantic commercial dairy farms. Total P...
