We studied the interaction of sodium dodecylbenzenesulfonate (SDBS) with Nile Blue (NB) and Safranine T (ST) by a spectral correction technique. The aggregations of NB and ST on an SDBS surface obeyed Langmuir isothermal adsorption. The adsorption ratios of NB and ST to SDBS were both 0.5, and the adsorption constants of the aggregates were 1.80 x 10(5) and 9.49 x 10(4). The aggregations were a...

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 ...

Precise estimation of sodium dodecylbenzenesulfonate (DBS) is essential for understanding its adsorption in soils, transport, toxicity, fate, and application the remediation contaminated soil groundwater. DBS can be easily identified by conjugated double bond systems benzene rings under ultraviolet (UV) spectrum a spectrophotometer. However, group components dissolved organic matter (DOM) also ...

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...

To match the relentless pursuit of three research hot points - efficient solar utilization, green and sustainable remediation of wastewater and advanced oxidation processes, solar-mediated thermo-electrochemical oxidation of surfactant was proposed and developed for green remediation of surfactant wastewater. The solar thermal electrochemical process (STEP), fully driven with solar energy to el...
