The concern with the accumulation of synthetic plastics in the environment is one of the reasons for the increasing interest in the development of biodegradable films. Among raw materials from renewable sources, starch is one of the most promising. In order to evaluate biodegradable films obtained from native starches (rice, potato and cassava), these were prepared by casting method with the ad...

The clay–microbial consortium is ubiquitous in the soil near mining area and plays an important role transport of heavy metals. In this study, Chlorella sorokiniana FK was separated from lead–zinc mine tailings. montmorillonite– system as a typical case applied to study Pb(II) biomineralization presence usually co-existent Ca(II) further reduce migration transformation environment. showed good ...

Palm oil mill effluent (POME) is the most produced waste among other types of waste, which around 60% in every 100% processing fresh fruit bunches containing heavy metals, namely ferrous metal (Fe). Montmorillonite (MMT) one best adsorbents used to reduce concentration Fe POME. In addition, this mineral also has a high cation fertilization capacity so that space between layers MMT able accommod...

the high hydrophilic property of biopolymer based plastics is one of the most important defects of them. blending biopolymers with compatible synthetic polymers and using nano particles such as nanoclay as nanofiller are improving methods that have been extensively considered in recent years. carboxymethyl cellulose (cmc) is one of the lowest cost biopolymers that have enormous applications in ...

Novel nanocomposite films based on amylose (AM) and Fe3+-montmorillonite (Fe3+–MMT) in the matrix of poly (vinyl pyrrolidone) (PVP) were fabricated by using a solution casting method. The X-Ray diffractional analysis indicated that an ion-exchange process occurred between Fe3+–MMT and PVP. Thermogravimetrical analysis (TGA), differential termogravivetrical analy...

The exchangeability of rare earth (RE) in weathered crust elution-deposited ores largely depends on its interaction with clay minerals, which may be significantly influenced by various cations. Therefore, the effects K<sup>+</sup>, Ca<sup>2+</sup> and Al<sup>3+</sup> RE<sup>3+</sup> adsorption desorption binding sites montmorillonite (MMT) were in...

The dielectric dispersion behaviour of montmorillonite (MMT) clay nanoparticles colloidal suspension in poly(vinyl pyrrolidone)-ethylene glycol (PVP-EG) blends were investigated over the frequency range 20 Hz to 1 MHz at 30°C. The 0, 1, 2, 3, 5 and 10 wt% MMT clay concentration of the weight of total solute (MMT+PVP) were prepared in PVP-EG blends using EG as solvent. The complex relative diele...

Nanocomposites have attracted a great deal of interest during recent years. Much research has been conducted towards the incorporation of clay particles in a polypropylene matrix. However, the effect of extrusion reprocessing on the material properties has not been studied in depth. In this study, composites of polypropylene (PP) reinforced with organic modified montmorillonite (MMT) (4 wt%) an...

Microwave heating potentially reinforces the muddy intercalation to eliminate slope failure. Montmorillonite has worst water resistance among components, which is a primary facet of inducing This study investigates mechanism shear strength and stability enhancement montmorillonite heated by microwave oven muffle furnace from room temperature 800 °C. Results show that mineralogical evolution can...

The effect that polymer molecular weight has on the dispersion of relatively polar montmorillonite (MMT) in nonpolar, unmodified high density polyethylene (HDPE) was examined. Polymer layered silicate (PLS) nanocomposites were prepared via melt compounding in a single screw extruder using three unmodified HDPE matrices of differing molecular weight and organically modified MMT (organoclay) in c...
