To catalyze the CVD growth of MWCNTs, a compound catalyst, namely, [Fe.sub.2][O.sub.3]/[Al.sub.2][O.sub.3], was synthesized through coprecipitation of ferric nitrate "Fe[(N[O.sub.3]).sub.3] x 9[H.sub.2]O" and aluminum nitrate "Al[(N[O.sub.3]).sub.3] x 9[H.sub.2]O." The chemicals, used in preparation of the metal catalyst, were supplied by SIGMA-ALDRICH.
The chemical reagents used in this experiment were ferric chloride hexahydrate (Fe[Cl.sub.3] x 6[H.sub.2]O), ferrous chloride tetrahydrate (Fe[Cl.sub.2] x 4[H.sub.2]O), and ferric nitrate nonahydrate (Fe[(N[O.sub.3]).sub.3] x 9[H.sub.2]O).
The precipitate was separated and washed several times and then oxidized to maghemite at 90[degrees]C for 30 minutes using ferric nitrate solution.
We have developed an ion chromatography (IC) assay using ultraviolet (UV) detection following post-column derivatization with ferric nitrate to determine phytate [inositol hexakis phosphate (iP6)] (1) (2) in wild rice samples and other diet composites.
Solution 1 (Maleic acid) Maleic acid 25 g Distilled water 1000 mL Solution 2 (Redox) Ferric nitrate 30 g Ferrous ammonium sulfate 80 g Citric acid 20 g Distilled water 1000 mL Solution 3 (Detergent) n-Dodecylamine acetate 3 g Synperonic-N 4 g Distilled water 1000 mL Solution 4 (Silver nitrate) Silver nitrate 200 g Distilled water 1000 mL Processing Procedure
The ferric nitrate solution, Fe[(N[O.sub.3]).sub.3] x 9[H.sub.2]O (12.5 mmol/L), was prepared in nitric acid (HN[O.sub.3] 1.5 mol/L).
Taft found that when one of these "iron-oxo" complexes reacts with ferric nitrate in a methanos solution, a green-brown color appears and then gives way to a yellow color when ether diffuses into the system.
