bubbled through at 0.2 dm 3 /min. No rise in the temperature due to the heat of the reaction was observed in any of the runs since the reactor was operated with low concentration of nitrate ions ( 100 mg/dm 3 NO 3 − ). No pressure control was required as

, particle size and NaOH concentration on the reaction conversion were investigated by converting the measurements of the amount of hydrogen evolved to overall conversion for H 2 /Al molar ratios of 1.55 ± 0.04. Also, they reported that the leaching follows

. Outside protonation is accelerated by increasing hydrogen ion concentration but not by general acids. Inside protonation of the deprotonated peptide nitrogen occurs simultaneously with metal–N(peptide) bond breaking [ 9 ]. This pathway is accelerated by

activity. Azo dyes have relatively large photoabsorption (extinction) coefficients and thus measurements in solution are easy even at very low concentrations. However, the fact that dyes absorb light indicates that the photoreaction could be induced by
