Sodium dodecyl benzene sulfonate (SDBS), Polyvinylpyrrolidone (PVP, MW 10 kDa), and NaCl were obtained from Sigma Aldrich. Microcalorimetry experiments were performed using a MicorCal ITC-VP at the University of Albany Proteomics Facility in Rensselaer, NY. SDBS was added to de-ionized distilled water, and placed into the injection syringe of the microcalorimeter, and added to the sample cell c...

Free nitrous acid (FNA) serving as a pretreatment is an effective approach to accelerate sludge disintegration. Also, sodium dodecylbenzene sulfonate (SDBS), a type of surfactants, has been determined at significant levels in sewage sludge, which thereby affects the characteristics of sludge. Both FNA pretreatment and sludge SDBS levels can affect short-chain fatty acid (SCFA) generation from s...

هدف از این مطالعه بررسی اثر سدیم دودسیل بنزن سولفونات (SDBS) بر برخی شاخص‌های زیستی (تنفس میکروبی، کربن زیتوده میکروبی، نیتروژن زیتوده میکروبی، فسفر زیتوده میکروبی، سهم متابولیک و سهم میکروبی) در یک خاک از منطقه اسکو بود. آزمایش به‌‌صورت اندازه‌گیری‌های تکرار‌شونده با فاکتور بین موردی SDBS در چهار سطح 0، 01/0، 05/0 و 25/0 درصد و متغیر درون موردی زمان در شش سطح 2، 7، 14، 30، 60، 90 روز در سه تکر...

Cyclophane BIMCP-1 undergoes ionic self-assembly with surfactant sodium dodecylbenzenesulfonate (SDBS) at a concentration far below its CMC value to form aggregates with spherical morphology. The rotational restriction of rings in these aggregates facilitates 32-fold enhancement in emission intensity (AIEE) to allow fluorescence based determination of SDBS with 4 μM (1.4 ppm) as the lowest dete...

Anionic surfactant solutions of sodium dodecylbenzenesulfonate (SDBS) and sodium dodecylsulfate (SDS) separate into two phases through cooling of the solution and the addition of salts. Thiourea (TU) reacts with many metals to form cationic complexes of [M(TU)(n)](m+); some of them extract into the SDBS phase. The separation was examined for lead and tin in commercially purchased solders. More ...

The phase behavior of a kind of pseudogemini surfactant in aqueous solutions, formed by the mixture of sodium dodecyl benzene sulfonate (SDBS) and butane-1,4-bis (methylimidazolium bromide) ([mim-C4-mim]Br2) or butane-1,4-bis(methylpyrrolidinium bromide) ([mpy-C4-mpy]Br2) in a molar ratio of 2 : 1, is reported in the present work. When [mim-C4-mim]Br2 or [mpy-C4-mpy]Br2 is mixed with SDBS in aq...

Solubilization of hexadecane by two surfactants, SDBS and Triton X-100, at concentrations near the critical micelle concentration (CMC) and the related aggregation behavior was investigated in this study. Solubilization was observed at surfactant concentrations lower than CMC, and the apparent solubility of hexadecane increased linearly with surfactant concentration for both surfactants. The ca...

Small-angle neutron scattering (SANS) and rheology are used to probe the wormlike micelles formed in mixtures of a cationic (cetyl trimethylammonium tosylate, CTAT) and an anionic surfactant (sodium dodecyl benzene sulfonate, SDBS). For a fixed composition of 97/3 CTAT/SDBS, the zero-shear viscosity η0 initially increases rapidly with surfactant concentration, but decreases beyond an intermedia...

Graphene and chemically modified graphenes were resolved by micellar electrokinetic chromatography (MEKC) using sodium dodecylbenzenesulfonate (SDBS) as a micelle matrix. Graphene was successfully dispersed in a micellar solution, and a consecutive and broad signal was obtained by the MEKC with a 20 mmol dm⁻³ aqueous SDBS solution for Graphene Nanoplatelets. Chemically oxidized graphene was les...

Polypyrrole films were electrosynthesized potentiodinamically on transparent fluorinedoped tin dioxide (FTO) substrates. Polymerization was carried out in the presence and in the absence of sodium dodecylbenzenesulfonate (SDBS) and single-walled carbon nanotubes (SWCNTs). The effect of the presence of SDBS and the addition of both asgrown and air-oxidized SWCNTs to the polymerization solution w...
