Bentonite-derived monolithic materials with and without distributed nanoscale turbostratic carbon, obtained by hot-pressing organobentonite and bentonite particles, respectively, in the absence of an added binder, exhibit exceptionally high dielectric loss while the electrical conductivity is relatively low. The combination of high dielectric loss and relatively low conductivity has not been pr...

The preferred method for the storage of spent nuclear fuel (HLW) is the disposal in deep geological formations. The repository will consist not only of the geological barrier but also of an engineered barrier and has to isolate the waste for at least 10 years from the biosphere [1]. In this barrier, several materials like concrete or bentonite are effective in retention of radionuclides. In mod...

Photocatalyst nanocomposites of ZnO/bentonite clay are synthesized by Solid-state ion exchange method. Ion exchange intercalation process of clays is used to incorporate the catalyst into the basal space of the layered structure of clays. The purpose of this study is to find a new method, which is focused on simplifying and saving time to prepare ZnO-bentonite composite with photocatalyst prope...

Na-bentonite was prepared and tested as an adsorbent for a dye (Reactive Blue2) removal from aqueous solution. The effect of various experimental parameters was investigated using a batch adsorption technique. In this manner, initial dye concentration, pH of the initial dye solution, temperature and time contact effects upon dye adsorption on Na–bentonite having a structural formula of (Si7.86 ...

In this study, organobentonites were prepared by modification of bentonite with various cationic surfactants, and were used to remove As(V) and As(III) from aqueous solution. The results showed that the adsorption capacities of bentonite modified with octadecyl benzyl dimethyl ammonium (SMB3) were 0.288 mg/g for As(V) and 0.102 mg/g for As(III), which were much higher compared to 0.043 and 0.03...

The aim of the study was to determine how soil contamination with diesel oil affected biochemical properties of soil and to determine whether the application of compost, bentonite or lime could recover the biochemical equilibrium of soil. The experiments were carried out in a greenhouse. Typical Eutric Cambisols soil formed from sandy loam was polluted with the following amounts of diesel oil: ...

The usage of wastes of bagasse would be admirable from environmental and solid waste management point of view. Thus, herein, this data set present a facile method for providing an adsorbent from mixture of bagasse-bentonite. The prepared adsorbent was applied to remove Pb2+ from aqueous solution. It was conducted in laboratory scale using completely randomized design with variations in mixed ma...

Thaumatin-like proteins (TLPs) and chitinases are the two main groups of pathogenesis-related (PR) proteins found in wine that cause protein haze formation. Previous studies have found that phenolics are also involved in protein haze formation. In this study, Sauvignon Blanc grapes were harvested and processed in two vintages (2011 and 2012) by three different treatments: (1) hand harvesting wi...
