Naphthalene sulfonate oxidizing

The electrochemical oxidation at BDD as final treatment in a combined two-step biological/electrochemical process was investigated by Panizza et al. (2006) for the removal of naphthalene sulfonates contained in infiltration water of an industrial site. Mono and disulfonate naphthalenes were easily removed in the biological step, whereas bio-refractory compounds with complex molecules were oxidised by electrolysis at BDD anodes. With this combination the energy demand was significantly lowered with respect to mat required in a single electrochemical step. 

Also, HPLC methods with electrochemical or fluorescent detection are used (H19, M3). In proteins, dityrosine can be estimated by immunochemical methods employing dityrosine-specific antibodies (K5). Measurements of o,o -dityrosine and o-tyrosine levels in rat urine express dityrosine contents in skeletal muscle proteins, and have been proposed as the noninvasive oxidative stress test in vivo. One should be aware, however, that A-formylkynurenine, also formed in protein oxidation, has similar fluorescence properties as dityrosine (excitation 325 nm, emission at 400-450 nm) (G29). Also, oxidation of mellitin when excited at 325 nm produces an increase in fluorescence at 400—450 nm, despite the fact that mellitin does not contain tyrosine. Oxidation of noncontaining Trp residues ribonuclease A and bovine pancreatic trypsin inhibitor with "OH produces loss of tyrosine residues with no increase in fluorescence at 410 nm (S51). There are also methods measuring the increased hydrophobicity of oxidized proteins. Assays are carried out measuring protein binding of a fluorescent probe, 8-anilino-l-naphthalene-sulfonic acid (ANS). Increase in probe binding reflects increased surface hydrophobicity (C7). 

Evidence has been accumulated that shows that transaldolase is a half the sites enzyme, in which binding of substrate to one site almost completely inactivates the other active site. As mentioned above, only 1 mole of substrate is bound to the active site, even though the enzyme is a dimer. In the presence of excess F-6-P a burst of one equivalent of G-3-P is produced followed by a slower conversion of F-6-P to G-3-P plus DHA. It appears therefore, that the blocking of one active site by adduct formation with dihydroxyacetone results in a modified second active site which is able to slowly cleave F-6-P [76], This second site behavior is identical to that found in transaldolase in which one active site has been modified by reducing the dihydroxyacetone adduct with borohydride. Photo-oxidation of one of the two histidine residues in isoenzyme III results in the loss of activity of the enzyme, as is consistent with half-sites reaction [77]. The dye l-anilino-8-naphthalene sulfonate on the other hand is bound with 2 moles of dye per mole of enzyme, indicating two binding sites for F-6-P [78]. 

Add solutions may be used for the preparation of certain naphthalene-sulfonic acids incapable of formation by other means. Both aliphatic and aromatic sulfides or hydrosulfides are oxidized to corresponding sulfonic adds. o-Iodobenzoic acid is oxidized to o-iodosobenzoic acid.

The fabrication of CP nanocomposites with metal oxides has become an important aspect for their potential applications in sensors and energy devices. The synergy between CPs and metal oxides provides the resultant nanocomposites with added functionalities compared to their individual parent materials. Wan and co-workers demonstrated that PANI/TiO, PANI/FejO and PANI/y-Fe Oj nanocomposites can be readily fabricated by a self assembling process [90-92]. The mechanism of the self-assembly can be related to the formation of micelles by (1-naphthalene sulfonic acid...

The so-called template free method was discovered accidentally by the group of Wan. " In this method, typically, a solution of aniline is mixed with a dopant such as (3-naphthalene sulfonic acid, camphorsulfonic acid (or no dopant at all) before the oxidant ammonium persulfate is added to the solution. The mixture is kept stirring at room temperature and the precipitated tubes are washed with water. While this method does not offer the same amount of control over the morphology and the inner and outer diameter of the tubes compared to the hard template methods, its key feature is simplicity and ease of preparation. ...
