Sodium sulfate is chemically very stable, being nonreactive toward most oxidizing or reducing agents at normal temperatures. At high temperatures, it can be converted to sodium sulfide by carbothermal reduction. It causes hot corrosion, which is the degradation of materials caused by the presence of a deposit or ash, predominantly …

Abstract The electrical resistance of PPy films synthesized in the presence of sodium dodecyl sulfate (SDS) surfactant and sodium sulfate (Na2SO4) as oxidant was analyzed in the temperature range of 24 to 80 °C. PPy was electrochemical synthesized for 20 and 60 min by using stainless steel electrodes immersed in a glass tubular reactor. A …
ABSTRACT In this study, the effect of sodium dodecyl sulphate (SDS) on Cu electrodeposition was evaluated using cyclic voltammetry. With the weak adsorption of SDS on Cu and Au surfaces, SDS slightly altered the cyclic voltammogram for Cu electrodeposition on these surfaces. However, the cyclic voltammogram on glassy …
Inhibition of sodium sulfate crystallization in the presence of phosphonates may promote the growth of efflorescence on porous ornamental stone, rather than damaging subefflorescence. The use of phosphonates may lead to more efficient preventive conservation of ornamental stone exposed to sodium sulfate damage.
In this paper, the reduction roasting of laterite ore in the absence or presence of sodium sulfate was carried out for nickel beneficiation by wet magnetic separation. Sodium sulfate is found to be capable of enhancing the reduction of laterite ore through liberating iron and nickel from Ni/Fe substituted-lizardite, as well as increasing the size of ferronickel …

The effect of the presence of an anionic surfactant, SDS (sodium dodecyl sulfate), on hydrate formation kinetics was also evaluated, showing that a combination of THF or DIOX and SDS is a very advantageous solution for accelerating hydrate formation. THF has been found to outperform DIOX as a hydrate promoter from both a …
When the laterite pellets were reduced at 1100C for 60 min, the average particle size of ferronickel grains was approximately 50 m in the presence of sodium sulfate, which far exceeded the size of ...

Poly(o-aminophenol) (POAP) was formed by successive cyclic voltammetry in monomer solution in the presence of sodium dodecyl sulfate (SDS) on the surface of a carbon paste electrode. The electrochemical behavior of the SDS–POAP carbon paste electrode has been investigated by cyclic voltammetry in 0.5 M HClO 4 and 5 mM K 4 …
Sodium dodecyl sulfate. SDS, also known as lauryl sulfate, is an ionic detergent that is useful for the rapid disruption of biological membranes as well as the breakdown of tissue architecture. Concurrently, SDS is a powerful inhibitor of both RNase and DNase activity. SDS is commonly prepared as either a 10% or a 20% (w/v) stock solution and ...

Amani and Firouzi [23] found that adding mono and divalent salts to the sodium dodecyl benzene sulfonate-water system significantly reduces the interfacial tension. Zhao et al. [24] examined the alkane-water IFT with sodium lauryl polyoxypropylene sulfate in the presence of salt and showed that the effect of Ca 2+ is …

The result shows that the value of CMC in the presence of sodium salts (CMC NaCl) is greater than that of sodium sulfate (CMC Na 2 SO 4). It is because Na 2 SO 4 easily creates a favorable condition for micellization than NaCl. Since the sulfate ion is a strong kosmotropic ion with high charge density than the chloride ion which has a …

In presence of sodium sulfate the viscosity values are larger than the ones of that salt in water from [22], but in presence of lithium sulfate the values are very close to the ones of this salt in water [23]. This shows boric acid has the same impact on the solution viscosity that the described for the density for both ternary systems.
