Central Composite

The optimization for process production of stainless steel corrosion inhibitor formulated with 1.3-Diphenyl-3-phenylsulfanyl-propan-1-one was studied using a 2 block central composite design including 3 factors (weight of catalyst, reaction time, and quantity of solvent). This process catalyzed by Fluorapatite coupled with their ease of use and reduced environmental problems makes them attractive alternatives to homogeneous basic reagents.

AbstractThe release of Am-241 during corrosion of the radioactive waste glass, JSS-A, has been studied in the presence of corrosion products and/or uncom-pacted bentonite. The corrosion behaviour of Am-241 has been analyzed using gamma spectrometry. Adsorption of Am-241 on bentonite is observed in all cases. The contents of Am-241 in centrifuged leachates are in most cases less than 1/100 of total values. The normalized elemental mass loss of Am increases initially with corrosion time, and the values in the presence of bentonite and corrosion products are larger than those in the presence of bentonite alone. This tendency is in agreement with results previously found for other elements. The release of Am is low, only about 10–20 % of the corresponding total mass loss.
