Dibutyl-Disulfide Montmorillonite (DD-MMT) was synthesized successfully and found to bean excellent adsorbent for Hg(II) removal. The fourier transform infrared spectroscopy (FTIR),x-ray diffraction spectrum (XRD) and scanning electron microscopy (SEM) were used tocharacterize properties of the absorbent. The effects of several parameters such as solutionpH, adsorbent dose, contact time and the...

The purpose of our study is to develop a controlled Naproxen releasing system for anti-inflammatory, analgesic treatments. Interpenetrating polymer network (IPN) type hydrogels were obtained by using natural polymers alginate and gelatin. prepared combining Alginate Gelatin in the presence Glutaraldehyde as crosslinker Montmorillonite (MMT) clay was used nano-dimensioned layered dopant. charact...

The development of thin-film composite membranes has gained more importance as they exhibit higher permeability, solute rejection and improved antifouling behavior. incorporation hydrophilic nanomaterials within the thin film reported to effectively increase hydrophilicity improve membrane performance. In this study novel nanofiltration were prepared by interfacial polymerization trimesoyl chlo...

Clay minerals have been recognized as one of the cheap and effective materials for wastewater remediation. Among various clay minerals, montmorillonite (MMT) has received much attention due to its wide availability, low-cost promising properties such high porosity, mechanical strength, cation exchange capacity. Additionally, MMT swelling properties. These features make it an ideal material reme...

Reactions occurring at silicate minerals play a significant role in controlling phenolic endocrine disrupting chemicals' bioavailability and mobility. However, the underlying molecular mechanisms for BPA (bisphenol A) BPS S) onto montmorillonite (MMT) remain poorly understood. To decipher molecular-level interfacial configuration dominant reaction mechanism, batch experiments, X-ray diffraction...

Clay minerals constituent an essential component of clayey rocks. Macroscopic mechanical behaviors those rocks can be significantly driven by local deformation and failure processes clay minerals. In this study, the behavior Montmorillonite (MMT) crystal at atomistic scale is investigated using molecular dynamics (MD) simulations. accordance with macroscopic laboratory tests, both triaxial comp...

In this work, we prepared the nafion/montmorillonite/heteropolyacid nanocomposite membranes for direct methanol fuel cells (DMFCs). The analyses such as X-ray diffraction (XRD), Fourier transform infrared (FTIR), and scanning electron microscopy (SEM) were conducted to characterize the filler dispersion and membrane structure in prepared nanocomposite membranes. XRD patterns of nafion-CsPW-MMT ...

The novel nanocomposite membranes were successfully prepared by the incorporation of different concentrations (5, 10, and 15 wt%) of montmorillonite (MMT) as a nanoadditive into a blend of chitosan/polystyrene (CS/PS) at a ratio of 3:1 on the basis of solution-casting method and they were subsequently used for the separation of phenol, p-chlorophenol, and 2,4-dichlorophenol from water through p...

Sedimentation of ultrafine silica particles that exist in acid leaching pulp and their separation from Pregnant Leach Solution largely determines the efficiency a hydrometallurgical process utilizing copper oxide ore. Thickener on larger scale can allow longer sedimentation, generating low overflow turbidity but high economic input. In this paper, flocculation behavior quartz sulfuric solution ...
