The excess of fluoride in water has given rise to serious health problems, reason why it is considered a priority pollutant to be removed from drinking water by the World Health Organization (WHO). Several investigations have shown that metal oxides possess a high fluoride adsorption capacity, a...

This work describes an environmentally-friendly procedure for the removal of manganese and fluoride from industrial wastewaters (IW) using layered double hydroxides (LDHs) and calcined layered double oxides (LDOs). Ternary Mg-Mn-Al LDHs (LDH-IW) were produced from IW containing a high concentrat...

Electrochemical activity of poorly conductive metal fluorides in Li-ion batteries is contingent on their nanostructuration to reduce diffusion lengths and increase reaction kinetics. In that regard, we optimize the synthesis and electrode formulation of MnF2 to enable sufficient electrochemical ...

Dry weight concentrations of lead in paints on a variety of structures in the urban and suburban environs of a British city (Plymouth, south west England) were determined in situ and ex situ by field-portable X-ray fluorescence spectrometry. Lead was detected in 221 out of 272 analyses, with ove...

Ultrathin nickel-iron carbonate hydroxides nanosheets/sulfides (denoted as NixFeyS/CH) are fabricated by sulfurizing treatment of nickel-iron carbonate hydroxide (NixFeyCH). The partial sulfuration of NiFe carbonate hydroxides by replacing the CO3/OH groups with the S group can well remain the h...

Globally, arsenic contaminated groundwater is a serious concern for human health. Previous studies have developed various methods to remove arsenic. But, most of them fail to selectively adsorb arsenic and regenerate. In this study, we developed an adsorbent, a cationic polymer gel loaded with i...

This study was aimed to evaluate the hydrogen sulfide (H2S) removal efficiency of an economic iron hydroxide-based adsorbent from simulated biogas mixture with an H2S concentration range of 500–10300 ppm. The properties of these porous materials such as crystal structures, surface patterns, sur...

In this report, a Cr regulated ternary CoFeCr hydroxide microsphere composite for enhanced water oxidation was fabricated using a facile electrodeposition method. The incorporation of Cr affects the oxidation state of Co and compared to the binary cobalt-iron hydroxide composite, the ternary com...

The use of micro-sized iron hydroxide adsorbents in mixed reactors is a promising technique for the removal of inorganic contaminants from wastewater within minutes of contact time. This study focusses on phosphate adsorption onto fine fraction granular ferric hydroxide (µGFH) and iron oxy(hydr...

Bimetallic (zinc-iron) hydroxides adsorbent (Zn-Fe hydroxide) was effectively synthesized through co-precipitation of bivalent zinc and trivalent iron at room temperature. The influences of Zn/Fe molar ratio, pH of a mixing solution of precipitating reagents, and aging temperature on adsorption ...

Cassava processing practices vary among communities and countries with implications for food safety. The study examined the microbiota and microbial metabolite profiles of 126 samples of sun-dried cassava products: grits, improved chips, improved flour, kivunde, and makopa from Tanzania, and man...

LiF-NaF-KF (46.5-11.5-42 mol %, FLiNaK) molten salt was used in the thermal diffusion (TD) process to form chromium carbide coatings on gray cast iron HT250 at 900 °C for 8 h. The structure and chemical composition of the coating were observed by scanning electron microscopy coupled with energy...

This study investigates the contamination of groundwater by chromium and fluoride around leather tanning industries. Major ions, chromium, δ53Cr/δ52Cr and fluoride were analyzed by advanced analytical methods. High degree of variation was observed in the concentration of chloride in groundwate...

Reaction of hydrated hydrazinium fluorochromate(III), [N2H6][CrF5]·H2O, with fluorine (F2) in anhydrous hydrogen fluoride (aHF) medium at room temperature yields completely amorphous CrF3-based materials with exceptionally high specific surface areas of 180–420 m2 g−1 (HS-CrF3). The stepwise r...

The feasibility of preparing oxide layer on a monocrystalline silicon (mc-Si) using the plasma electrolytic oxidation (PEO) process was investigated in this study and the influence of adding boric acid to the silicate based electrolyte on the formation and the properties of the oxide layer was e...

The boron element possesses a range of different effects on living beings. It is essential to beneficial at low concentrations, but toxic at excessive concentrations. Recently, some boron-based compounds have been identified as promising molecules against Trypanosoma brucei, the causative agent ...

The objectives of the present study were to evaluate the antimicrobial effect of boric acid (BA) on Salmonella enteritidis colonization, intestinal permeability, total intestinal IgA levels, and cecal microbiota composition in broiler chickens. For this purpose, sixty day-old-chicks were randoml...

IR and Raman measurements were carried out for boric acid in water and DMSO. IR-active bands at 1410 and 1150 cm−1, which have been related to the E′ representation, were not observed in the Raman spectrum of the acid in water. At the same time, the 1060 cm−1 band, which should be Raman-active ...

A Eu-metal organic framework (Eu-MOF) probe with dual-emission was reported for the ratiometric fluorescence detection of H2O2 and glucose. Because of the special nucleophilic reaction between boric group and H2O2, Eu3+ and 5-boronobenzene-1,3-dicarboxylic acid (BBDC) were selected to synthesize...

Present studies were carried out to investigate the potential of boric acid to extend storage the life of pear (Pyrus pyrifolia L.) cv. ‘Patharnakh’ fruits. Pear fruits were dipped in aqueous solutions of different concentrations (0- water dip, 1–3%) of boric acid for 5 min and thereafter sto...
