Sulfate radical (SO4(•-)) is a strong, short-lived oxidant that is produced when persulfate (S2O8(2-)) reacts with transition metal oxides during in situ chemical oxidation (ISCO) of contaminated groundwater. Although engineers are aware of the ability of transition metal oxides to activate persulfate, the operation of ISCO remediation systems is hampered by an inadequate understanding of the f...

During sulfur (S) deprivation, the unicellular alga Chlamydomonas reinhardtii exhibits increased expression of numerous genes. These genes encode proteins associated with sulfate (SO4(2-)) acquisition and assimilation, alterations in cellular metabolism, and internal S recycling. Administration of the cytoplasmic translational inhibitor cycloheximide prevents S deprivation-triggered accumulatio...

In this work, 75 quality protein maize (QPM) inbred lines were evaluated for aluminum tolerance using a nutrient solution assay in laboratory and soil-based technique greenhouse tunnel. The experiment was set up completely randomized design with three replications the laboratory, complete block used greenhouse. Aluminum toxicity generated by amending 600 µM of sulfate (Al2 [SO4]3) Al2 [SO4]3 ap...

The dicopper(II) complex [Cu2(R'SSR)2(SO4)2] (1), where R'SSR is a Schiff base, has been prepared from the reaction of CuSO4.5H2O with the Schiff base N,N'-1,1'-dithiobis(ethylenesalicylaldimine)(H2RSSR) and structurally characterized by X-ray crystallography. The crystal structure of 1 shows two {Cu(R'SSR)}2+ units linked by two sulfate ligands each showing a eta3,mu2-binding mode. The Cu...Cu...

In this work, the results of gas phase cyclohexane photocatalytic oxidative dehydrogenation on MoOx/SO4/TiO2 catalysts with DRIFTS analysis are presented. Analysis of products in the gas-phase discharge of a fixed bed photoreactor was coupled with in situ monitoring of the photocatalyst surface during irradiation with an IR probe. An interaction between cyclohexane and surface sulfates was foun...

The sulfate radicals (SO4•−)-based advanced oxidation process is an efficient way to degrade stubborn pollutants. However, the degradation products of 2,4-dinitrotoluene and effects different natural water matrices on by persulfate/Fe2+ are largely unknown. In this study, kinetics were investigated in matrices. can be divided into rapid-slow reaction stages, which was suitably described pseudo-...

Renal proximal tubular sulfate reabsorption is mediated by brush border membrane Na+/sulfate-cotransport and basolateral Na(+)-independent sulfate transport. Injection of rat kidney cortex mRNA into Xenopus laevis oocytes induced Na(+)-dependent as well as Na(+)-independent sulfate transport. The inhibition pattern of Na(+)-dependent uptake coincided with that known for the brush border membran...
