In this study, the elucidation of the toxicity mechanism was undertaken regarding the IC(50) of the oxygen uptake rate (OUR) with relevance to the biosorption as a toxicity evaluation of chemical substances for activated sludge (AS). At the IC(50) of<100 mg/l, malachite green (MG) and crystal violet (CV) were confirmed in the group showing relatively strong OUR inhibition. These dyes were marke...
In the title sulfonate derivative, C(24)H(26)O(9)S(3), all atoms apart from those of one of the 4-methyl-benzene-sulfonate residues lie approximately in a disc; the dihedral angles between the approximately orthogonal benzene ring and those in the plane are 74.53 (9) and 67.79 (11)°. In the crystal, mol-ecules are consolidated into the three-dimensional architecture by C-H⋯O inter-actions. One ...
In this study, linear alkyl-benzene calcium sulfonate nanoparticles were made using linear alkylbenzene. Calcium sulfonate nanoparticles are widely used as an additive in a variety of engine oils and have cleansing, anti-wear and anti-oxidant properties and anti-corrosion properties. In this method, a sulfonation set up was constructed and sulfonation reaction was carried out both directly and ...

optimal conditions for enhancing sodium dodecyl sulfate biodegradation by pseudomonas aeruginosa kgs
the anionic surfactant sodium dodecyl sulfate (sds) was degraded by novel strain ofpseudomonas aeruginosa kgs under accession no. jq328193, which was isolated from carwash wastewater. the purpose of this research was to study different optimization conditionsrequired for enhancing the biodegradation of sodium dodecyl sulfate p. aeruginosa kgs.influence of different physicochemical factors such ...
Foam drainage gas production is a technology for low-pressure well in domestic and abroad industries. In Qinghai Oilfield’s Sebei Gasfield, sand existence often occurs during production. order to reveal the impacts of formation sands on production, lab test was conducted make study foam performances different agents case existence. A laboratory employed under varies scenes existence, recovery. ...
A sensitive, selective and rapid method for the determination of nickel based on a rapid reaction of nickel(II) with 2-(2-quinolylazo)-5-diethylaminoaniline (QADEAA) has been developed. In the presence of pH = 6.0 ammonia-ammonium chloride buffer solution and sodium dodecyl sulfonate (SDS) medium, QADEAA reacts with nickel to form a violet complex having a molar ratio of 1:2 (nickel to QADEAA)....
