A dendrimer amphiphilic polymer (A-D-HPAM) was synthesized by aqueous solution polymerization of acrylic acid (AA), acrylamide (AM), 2-acrylamido-2-methyl-1-propane sulfonic (AMPS), hydrophobic monomer cetyl dimethyl allyl ammonium chloride (DMCAAC-16), and skeleton GA1.0, using persulfate sodium bisulfite as initiators. The chemical structure A-D-HPAM was, respectively, analyzed Fourier transf...

this paper presents efflux time experiments performed in the absence and presence of aqueous solutions of drag reducing agents (dras) when a liquid is emptied from a large open cylindrical storage tank through an exit piping system. the drag reducing agents studied are dodecyl benzene sulfonate anionic surfactant and a mixed solution of surfactant and sodium chloride counter ion. the variables ...

Abstract Coking coal dust is extremely hydrophobic; therefore, combination with droplets in the air difficult and suppression challenging. Here, a suppressant spray for coking was studied order to improve of dust. Based on monomer optimization compounding analysis, two surfactant monomers, fatty alcohol ether sodium sulfate (AES) dodecyl benzene sulfonate (SDBS) were selected as components supp...

In the present work, the synthesis of Barium hexaferrite (BaFe12O19) nanoparticles in thepresence of a large excess amount of OH− anions by the hydrothermal method in the presence and absence of surfactants such as Sodium dodecyl benzene sulfonate and Triton X-114 was reported. The optimized temperature in the absence of surfactant was determined (200 °C) and then Barium hexaferrite nanoparticl...

Resource utilization of SO2 from flue gas is a key challenge for the green development smelting industry. Recovery sulfur resources in form elemental (S0), which has high market demand and current focus field treatment, can reduce solid waste desulfurization. In this study, it was found that Pb as cathode material had good catalytic activity electrochemical reduction selectivity towards sulfur....

To improve the dielectric properties and thermal conductivities of epoxy resins (EP), titanium dioxide superfine powders with microspheres structure (S-TiO2) were prepared via a hydrothermal process based on sodium dodecyl benzene sulfonate hydroxyl silicate. The different content S-TiO2 was then employed as modifiers to add into EP resin prepare S-TiO2/EP composites. morphology observed by X-r...

In order to investigate the tolerance of an anoxic-oxic (A/O) process for changing refractory organics in electroplating wastewater, optimize technological parameters, and reveal microbial characteristics, a pilot-scale A/O was carried out community composition analyzed by high-throughput sequencing. The results indicated that better achieved sodium dodecyl benzene sulfonate, removal efficienci...

CO2 geo-storage in basaltic formations has recently been identi?ed as a viable option to rapidly dispose large quantities of , hence mitigating anthropogenic emissions. However, it shown that basalt is weakly water-wet or intermediate-wet at typical storage conditions, which reduces capillary trapping capacities and increases lateral vertical spreading the plume; these effects increase project ...

Abstract With hydrophobic associating polymer (BCG-1) and anionic surfactant sodium dodecyl benzene sulfonate (SDBS) solution as the object, this work studies different concentration on influence law of fluid properties examines sand sedimentation rate correlation properties. After liquid was tested by electron microscope rheometer, it found that interaction between is with phases, which provid...
