The adsorption capacity of sepiolite towards the removal heavy metal ions from aqueous solution was studied in this work, with equilibrium data being obtained a bath adsorber. sample chemically stable over pH range 2–12, but dissolved acidic solutions values less than 2. Langmuir isotherm gave better fit experimental data, since average absolute percentage deviation lower that Freundlich isotherm. decreased following order: Cr(III) > Cd(II) Cu(II) Zn(II) Ni(II) Ag(I). Increasing...
Coupling Bi 2 WO 6 /BiVO 4 semiconductors to construct heterostructures improves charge transfer and restricts the recombination of photogenerated electron–hole pairs, boosting photocatalytic activity.
The adsorption capacity of uncalcined and calcined layered double hydroxide (LDH) for fluoride removal was studied in this work. LDH synthesized by a co-precipitation method at various temperatures. equilibrium data on the LDHs were obtained batch adsorber, Freundlich isotherm model showed better fit to data. chemically stable over pH range 5–12, but readily dissolved when below 5. decreased raising due electrostatic interactions, presented maximum 25 °C. influenced calcination temperature...
An organobentonite was prepared by adsorbing the cationic surfactant hexadecyltrimethylammonium bromide (HDTMA) onto surface of a calcium bentonite. The adsorption capacity towards 2,4-dichlorophenoxyacetic acid (2,4-D), phenol and dichromate ion (HCrO − 4 ) from aqueous solutions investigated. Langmuir isotherm gave reasonable fit to experimental data for sorption 2,4-D, HCrO organobentonite. equilibrium 2,4-D demonstrated bimodal concentrations greater than 650 mg/l. sorbing considerably...
Ring opening polymerization (ROP) of hexamethylcyclotrisiloxane (D 3 ) and octamethylcyclotetrasiloxane 4 was promoted by acid‐treated synthetic natural silica‐aluminates. Silica‐alumina (1:3 Si/Al molar ratio) obtained using a simple economic route from precipitation aluminum sulfate solutions. The material treated in an acidic medium to improve the content acid sites successfully tested as inorganic catalyst for ROP D or cyclosiloxanes. Natural bentonite used similar manner. Once reaction...
Abstract Different carbon materials, such as activated and aerogel, are used widely adsorbents due to their high surface area. Carbon nanospheres (CNS), a nanometric form of carbon, commonly in drug delivery, heterogeneous catalysis, encapsulation catalysts. However, these properties sill can be improved by N doping. On the other hand, heavy metal ions considered one most toxic aquatic pollutants, removal is current line research. Thus, objective present study was reduce diameters CNS,...
Objectives. Contamination with heavy metals has augmented in last decades due to several factors. So, scientific community a challenge develop new and more efficient methods for contaminants removal. Electroadsorption is one of investigated techniques promising results. The main this technique determination optimal parameters, such as electrode material, time conditions adsorption. Material electroadsorption must fulfil some criteria: high electroactive area, low electrical resistance...
Electrochemical supercapacitors are widely investigated as energy storage devices.The major part of research is dedicated to electrode materials development.Herein, we describe an electrochemical synthesis 6 carbon-based from graphite.Influence parameters (temperature and distance between electrodes) on resulting was investigated.The were tested be used material in storing system with phosphate buffer (pH=7) supporting electrolyte.Resulted showed a good stability high operating voltage range...
Objective. Different types of nanoparticles, including carbon ones, were tested for a variety biological applications. Alongside with promising results, some undesired side effects disclosed. Most studies performed on highly functionalized nanospheres, so the main objective this study was to assess cytotoxicity unfunctionalized nanospheres synthetized by sol-gel method. We hypothesize that material will present different cytotoxic pattern cell culture. Methodology. 3 nanosphere materials...
