The preparation, structures, and spectroscopic properties of several molecular complexes and a one dimensional chain are described. A one-dimensional {trans-CrII(DMF)2(OTs)2}n (1) chain and mononuclear complexes of trans-[MII(OTs)2(DMF)4] (MII = Fe, 2; Co, 3) and [NiII(DMF)6][OTs]2 (4) stoichiom...

A single crystal of p-toluidine p-toluenesulfonate (PTPT) has been grown by slow evaporation solution technique (SEST) at room temperature. Single crystal X-ray analysis confirms that grown crystal belongs to the monoclinic structure with space group P21. Intermolecular interactions and fingerpr...

Crystalline silver(I) coordination compounds [Ag2(HL)4(C6H5SO3)2]·0.5C3H7OH (1) and [Ag2(HL)(L)(CH3C6H4SO3)] (2) (HL = 3-(prop-2-en-1-yl)-2-thioxoimidazolidin-4-one) have been obtained using silver(I) salts and the organic ligand HL. Three independent Ag(I) atoms in crystal 1 adopt exclusively ...

In the present study, we synthesized novel benzimidazole–silver(I) complexes (2a–d) by the interaction of 1-benzyl-3H-benzimidazolium p-toluenesulfonate derivatives (1a–d) and Ag2O in order to investigate their anticancer properties. All the salts and complexes were fully characterized by 1H ...

The removal of flurbiprofen (FLU) by electrosynthesized ferrate(VI) ion and electrocoagulation (EC) process was investigated. The degradation of FLU by ferrate(VI) was affected by pH, applied ferrate(VI) dose and initial drug concentration. Complete removal of FLU was achieved at pH 4 and applie...

This study systematically investigated the degradation of tetrabromobisphenol A (TBBPA) by ferrate (VI) oxidation. The reaction kinetics between ferrate (VI) with TBBPA were studied under pseudo-first-order conditions in the pH range 5.5–10.5. Then, a series of batch experiments were carried ou...

Bisphenol S (BPS) and bisphenol AF (BPAF) were increasingly consumed and these compounds are resistant to environmental degradation. Herein, ferrate oxidation of BPS and BPAF was investigated, and biodegradability of the oxidation products was examined. The second-order reaction rate constants o...

p-Arsanilic acid (p-ASA) and roxarsone (ROX) are two major phenylarsenic feed additives that are still widely used in many countries, and the land application of animal waste containing these compounds could introduce large quantities of arsenic into the environment. In this study, we proposed a...

The degradation of parathion (PTH) by ferrate(VI) was investigated to evaluate the potential application of this iron-based chemical oxidant in water treatment. A series of kinetic experiments were conducted to examine the effects of operational parameters like solution pH, oxidant dose and temp...

This study investigated the effects of ferrate and ozone pre-oxidation on disinfection byproduct (DBP) formation from subsequent chlorination or chloramination. Two natural waters were treated at bench-scale under various scenarios (chlorine, chloramine, each with ferrate pre-oxidation, and each...

In this study, the strategy of combining radiation with ferrate oxidation was proposed to decrease the adsorbed dosse and enhance the mineralization of carbamazepine in aqueous solution. Compared to single radiation (800 Gy), the combined process of ferrate pretreatment and radiation required lo...

Distinct naphthenic acid (NA) species were isolated from oil sands process water (OSPW) into 20 fractions via silver-ion solid phase extraction, prior to treatment using potassium ferrate(VI). Untreated and treated fractions F1–F20 were characterized using ultra performance liquid chromatograph...

Arsenic compounds are carcinogenic to humans and are typically removed from contaminated water using various sorbents. The ionic composition plays a significant role in arsenate removal efficiency during the process of water remediation. Here, we quantify the effects of natural ions (chlorides, ...

In this study, ferrate intercalated Ca/Al-layered double hydroxide (Ferrate-LDH) was synthesized and characterized for water treatment. In the new Ferrate(VI) material, ferrate was stably present in the LDH interlayers, in agreement with results of the Density Functional Theory simulation. The o...

The acid–base and complexation properties of cellulose degradation products were evaluated using capillary electrophoresis. Alteration of the electrolyte pH was carried out to modify the degree of dissociation of the solutes ((hydroxy)carboxylic acids). The subsequent change of the effective mo...

Hydrothermolysis of d-glucose, cellobiose, and β-cyclodextrin leads to the formation of small amounts of 3-deoxyhexonic acids. These acids are known to be produced by the alkaline degradation of carbohydrates. The formation under neutral hydrothermal conditions of the 3-deoxyhexonic acids provi...

SummaryBarium ions precipitate inorganic as well as organic sulfate compounds and they can be detected by a reaction with sodium rhodizonate. In this work, we describe the use of a barium method for the selective demonstration of sulfated glycosaminoglycans in cytoplasmic granules of mast cells ...

The Reformatsky reagent tert-butoxycarbonylmethylzinc bromide adds in high yields to N-sulfonylimines, e.g. 1a–1d, derived by condensation of benzaldehyde dimethyl acetal with methanesulfonamide, toluene-4-sulfonamide, 4-(methoxycarbonyl)benzenesulfonamide and sulfamide: the products are protec...

SummaryUsing a novel in vitro technique, whereby microsomal enzymes were embedded in an agar layer to prolong their viability, 1,1-bis(p-chlorophenyl) ethylene(DDNU), a mammalian metabolite of 1,1-bis(p-chlorophenyl)-2,2,2-trichloroethane (DDT), was converted by microsomal mono-oxygenases of mou...

BackgroundWhile producing good-quality analgesia, µ-opioid (MOP) receptor activation produces a number of side-effects including tolerance. Simultaneous blockade of δ-opioid (DOP) receptors has been shown to reduce tolerance to morphine. Here, we characterize a prototype bifunctional opioid H-...
