2-amino-n-benzthioazolyl benzamide (abtb) was synthesized, characterized and used for thefabrication of a potentiometric sensor for cu2+ metal ions. the electrode exhibits linear response to cu(ii) over a wide concentration range (4.79×10 -8 – 1.85×10 -1 m) with nernstian slope of 30 ± 1.5 mvper decade. the electrode can be used in the ph range from 2 to 9. it has a fast response time of about1...

Unmodified natural silicates (bentonite, kaolin, clinoptilolite and diatomites) were tested as adsorbents for the organic pollutants in water tables using Methylene Blue (MB) model adsorbate. Among selected materials, bentonite adsorbed much 237 mg/g, confirming its excellent suitability pollutant removal. Spectral evidence confirmed successful MB immobilization at surface. Furthermore, thermal...

this study presents a comparison between aluminum and iron plate electrodes on phosphate removal from aqueous solutions by electrocoagulation process. the effectiveness of main operational parameters such as initial ph, initial phosphate concentration and current density were examined. in addition, treated solution and sludge characteristics, energy consumption and electrode mass depletion were...

in this study, removal of methylene blue by electro-coagulation method using aluminum and iron electrodes was investigated. the influence of the operating parameters such as contact time, current density, anode type, inter-electrodes distance, initial and final ph and energy consumption rate was determined. dye removal was increased with increases in solution ph, current density and contact tim...

We developed micropore membrane inlet mass spectrometer (MMIMS) probes to rapidly measure inert-gas partial pressures in small blood samples. The mass spectrometer output was linearly related to inert-gas partial pressure (r(2) of 0.996-1.000) and was nearly independent of large variations in inert-gas solubility in liquid samples. We infused six inert gases into five pentobarbital-anesthetized...

Abstract Activated porous carbon was synthesized from methylcellulose biopolymer through a two-step mechanism involving H 3 PO 4 as an activating agent and then thermally carbonized in tubular furnace under inert atmosphere at 850 °C. The product next rinsed with strong HCl, neutralized deionized water, dried oven 80 Then, to fully understand the behavior of activated carbon, it characterized u...

Metastable 1T? MoTe2 has attracted much attention as a cost-effective electrocatalyst for hydrogen evolution reaction (HER) in recent years. However, few studies were done over common stable 2H phase because it often exhibits inferior performance. Herein, with S-doped Te vacancies been synthesized by one-step telluride conversion of 1T MoS2 at 700°C under Ar/H2 atmosphere. It is demonstrated th...

Dissimilar metals have found wide use in electric power generation, electronics, reactors, nuclear, petrochemical, chemical industries, civil construction, vessels, and heat exchange as well several other industries. TIG welding (Tungsten Inert Gas Welding) is a type of that uses tungsten the electrode material not consumed. Brazing way joining metal materials through heating process with an ad...
