Enrichment and Isolation of Naphthalenesulfonic Acid-Utilizing Pseudomonads [PDF]

Applied and Environmental Microbiology, 1981
Naphthalenesulfonate-degrading bacteria were obtained by continuous enrichment from a naphthalene-degrading population from sewage. In addition to naphthalene, Pseudomonas sp. A3 can utilize 2-naphthalenesulfonate (2NS) and Pseudomonas sp. C22 can utilize both 1-naphthalenesulfonate (1NS) and

Microbial desulfonation of substituted naphthalenesulfonic acids and benzenesulfonic acids [PDF]

Applied and Environmental Microbiology, 1987
Sulfur-limited batch enrichment cultures containing one of nine multisubstituted naphthalenesulfonates and an inoculum from sewage yielded several taxa of bacteria which could quantitatively utilize 19 sulfonated aromatic compounds as the sole sulfur source for growth. Growth yields were about 4 kg of protein per mol of sulfur.

Zwitterionic 5-amino-2-naphthalenesulfonic acid [PDF]

Acta Crystallographica Section E Structure Reports Online, 2004
The crystal structure of 5-amino-2-naphthalene­sulfonic acid (1,6-Cleve's acid), C10H9NO3S, shows the presence of a sulfonate–aminium group zwitterion, viz. 5-ammonio-2-naphthalene­sulfonate. All aminium H atoms are involved in head-to-tail intermolecular hydrogen-bonding interactions with separate sulfonate O-atom acceptors, giving a three-dimensional

Separation of naphthalenesulfonates by capillary zone electrophoresis.

BUNSEKI KAGAKU, 1996
The separation behavior of naphthalenesulfonates (NSs) by capillary zone electrophoresis (CZE) has been investigated. Since the structural isomers of naphthalenemonosulfonate (NMS) and naphthalenedisulfonate (NDS) were identical at normal pH, modifiers such as surfactants and water soluble polymers were added to the electrophoretic buffer solution (20 ...

Decomposition of 2-naphthalenesulfonate in electroplating solution by ozonation with UV radiation [PDF]

Journal of Hazardous Materials, 2005
This study investigates the ozonation of 2-naphthalenesulfonate (2-NS) combined with UV radiation in the electroplating solution. 2-NS is commonly used as a brightening and stabilization agent in the electroplating solution. Semibatch ozonation experiments were conducted under various reaction conditions to study the effects of ozone dosage and UV ...

6,6′-Oxybis(2-Naphthalenesulfonic Acid) in Schaeffer’s Salt

Journal of AOAC INTERNATIONAL, 1971
Abstract An unknown present in Schaeffer’s salt is identified as 6,6′-oxybis (2-naphthalenesulfonic acid), DONS. A method is presented for the determination of DONS in commercial Schaeffer’s salt by column chromatography and UV spectrophotometry.

Decomposition of 2-naphthalenesulfonate in aqueous solution by ozonation with UV radiation [PDF]

Water Research, 2002
This study investigates the ozonation of 2-naphthalenesulfonate (2-NS) combined with ultraviolet (UV) radiation. Naphthalenesulfonic acids are of importance as dye intermediates for the dye and textile auxiliary industries. Its derivatives, such as 2-NS, have been found in rivers and tannery effluents causing pollution problems.
