Due to the huge amount of lead (Pb(II)) containing wastewater from the industrial effluent production, an innovative material is welcome to minimize the contamination level. Assuming mesoporous conjugated adsorbent (MpCA) fabrication, the novel organic ligand was synthesized and then subsequentl...

A novel synthesized nanostructured ion-imprinted polymer (IIP) was investigated for the determination of trace amount of thallium(I). For this purpose, the thallium(I) IIP particles were synthesized using methacrylic acid (MAA) as the functional monomer, ethylene glycol dimethacrylate (EGDMA) as...

The partial pressure of thallium(I) hydroxide TlOH in equilibrium with gaseous thallium(I) oxide Tl2O and H2O(g) was studied by measuring the rate of loss of mass of crystalline thallium(III) oxide Tl2O3 into flowing (water + oxygen)(g) and (water + oxygen + argon)(g) streams at atmospheric pres...

Three new calixarene Tl+ ionophores have been utilized in Tl+ ion-selective electrodes (ISEs) yielding Nernstian response in the concentration range of 10−2–10−6 M TlNO3 with a non-optimized filling solution in a conventional liquid contact ISE configuration. The complex formation constants (lo...

In the present paper, for the first time, the integrated three-electrode screen-printed sensor with in situ plated bismuth film carbon working electrode was applied for the ultratrace determination of thallium(I) (Tl(I)). Under optimized conditions extremely low limits of detection were reached,...

Continental weathering plays a key role in modifying the geochemical budget of terrestrial reservoirs. Laterites are the products of extreme sub-aerial continental weathering. This study presents the first investigation of thallium (Tl) abundances and stable isotopic compositions of lateritic te...

Microstructures of [Tl2(μ2-ATA)]n (1), [HATA = 2-aminoterephthalic acid], supramolecular polymer was synthesized by sonochemical process (1S) and used as new precursor for preparation pure phase of thallium(III) oxide microstructures. [Tl(μ2-dcpa)]n (2), [Hdcpa = 2,4-dichlorophenoxyacetic acid...

Thallium is a highly toxic pollutant to mammals and its removal from water is increasingly gaining attention. In order to effectively remove thallium(I), a much more mobile and difficult to be removed thallium species, nanostructured titanium peroxide was facilely synthesized via an oxidation co...

Respirable sintering dust was an abundant and hazardous waste arrested by electrostatic precipitators from iron and steel industry. In this study, this waste was first found to contain 0.3% Rb, existing in the form of chloride and making it a promising Rb extracting material. Meanwhile, 95.24% o...

Rubidium was predominately identified in boron clay (BC) as a result of the analyses of trace elements in boron industrial wastes that were investigated. In the first step, rubidium in the BC was removed from the solution by leaching in 1 M H2SO4 for 2 h. After a filtering operation, rubidium wa...

Kinetics of rubidium extraction by 4-tert-butyl-2-(α-methylbenzy) phenol (t-BAMBP)/sulfonated kerosene in brine solutions were investigated using the rising single drop technique. Parameters affecting the mass transfer mechanism, including the interfacial area, initial alkalinity of aqueous pha...

The ability of 4-tert-butyl-2-(α-methylbenzyl) phenol (t-BAMBP) to separate rubidium from potassium in an alkaline solution obtained from the treatment of rubidium ore has been assessed. The effects of various factors on extraction, scrubbing, and stripping were investigated under batch test co...

The reaction kinetics for the leaching of low-grade scheelite concentrate was investigated in an autoclave with sodium hydroxide in the presence of phosphate. The effects of stirring speed (300−600 r/min), reaction temperature (353−383 K), sodium hydroxide concentration (1.69−6.76 mol/L) and pho...

A drowning-out crystallization process was designed to produce purified lithium oxide monohydrate. The study started with the development of the ternary phase diagram for the LiOH – water–ethanol system. This was followed by process conceptualization integrating crystallization, downstream pro...

The magnetic layered double hydroxide lithium-aluminum was prepared by the combination of two simple procedures: co-precipitation method for the magnetite and dissolution of aluminum powder under strong basic conditions in order to form the LDH. The magnetic LDH was characterized by powder X-ray...

Extracting lithium from salt lakes and preparing lithium hydroxide could provide important commodities for the economic development in future. In this work, a complete system was divided into two steps of selectrodialysis (SED) and selectrodialysis with bipolar membrane (BMSED) to treat salt lak...

Hydrogen sulfide (H2S) can exert different effects on the gastrointestinal tract by modulating ion channels. Previously, we found that H2S donor sodium hydrosulfide (NaHS) regulates colonic motility through L-type calcium channels, but the molecular mechanism remains unknown. The present study w...

Hydrogen sulfide and hydrogen cyanide are known to compromise mitochondrial respiration through inhibition of cytochrome c oxidase and this is generally considered to be their primary mechanism of toxicity. Experimental studies and the efficiency of current treatment protocols suggest that H2S m...

A new method was reported for surface modification of an up-conversion luminescence material with hydrosulfide group. The factors that may influence the surface modification, such as reaction time, amount of catalyzer and modifier, and reaction solvent, were investigated. The optimal conditions ...

Temperature extremes represent an important limiting factor to plant growth and productivity. Low concentration of hydrogen sulfide (H2S) has been proven to function in physiological responses to various stresses. The present study evaluated the effect of foliar application of wheat seedlings wi...
