The degradation and mineralization of the plant growth regulator 2-(1-naphthyl)acetamide (NAD) was studied by excitation in the presence of the catalyst polyoxometalate decatungstate anion (W10O324−) in aqueous solution under UV (365nm) or simulated solar light exposure. Our results indicate that the photocatalytic degradation of NAD is dependent on molecular oxygen concentration: in aerated conditions,...
The photophysical properties of the widely used plant growth regulator 2-(1-naphthyl) acetamide (NAD) were studied in water and representative organic solvents (ethanol, ethylene glycol, acetonitrile, chloroform, 1,4-dioxane) employing steady-state and time-resolved spectroscopy. Quantum yields and lifetimes of fluorescence, phosphorescence and triplet formation and triplet–triplet absorption spectra...
The photochemical degradation of 2‐(1‐naphthyl) acetamide (NAD) in aqueous solution using simulated sunlight excitation as well as UV light within the 254–300 nm range was investigated to obtain an insight into the transformation mechanism that could occur under environmental conditions. Several photoproducts were identified using HPLC/MS/MS techniques. The degradation quantum yield was found to be...
