Natural rubber latex-clay nanocomposite: use of montmorillonite clay as an alternative for conventional CaCO3

Natural rubber-clay nanocomposites

The mechanical properties of non-vulcanized natural rubber and dialyzed natural rubber-clay nanocomposites have been studied by uniaxial deformations to evaluate the reinforcement efficiency of the clay. We show that while non-rubber molecules contribute to auto-reinforcement, removal of these molecules improves significantly the performance of clay as reinforcement agent. These mechanical prop...

Aqueous Phase Removal of Fluoride as Fluorosis agent Using Montmorillonite Clay as Natural Nanoadsorbent

Natural nanomaterial; Montmorillonite Clay was collected and purified and then applied in the removal of Fluoride. The Montmorillonite Clay was grounded and 150g was weighed and refluxed in 500mL 1MHCl at 1200C for one hour thirty minutes and activated Montmorillonite Clay was obtained. Flouride was determined with the aid of SPADNS Reagent (2-parasulfophenylazo)-1,8-dihydroxy-3,6-naphthalene d...

Clay Minerals as Natural Nanosheets

Particles with nanometer dimensions (nanoparticles) are all around us. The finest particles of sand are blown by the wind over thousands of kilometers. The finest particles of soils are either eroded by the wind in extremely dry conditions or by water under wet conditions and deposited hundreds of kilometers or more from the origin. The air contains nanoparticles of carbon, ice, and oxides and ...

Fluoride adsorption studies of montmorillonite clay

Batch adsorption studies were conducted to determine the effects of contact time and temperature on fluoride removal by montmorillonite clay at neutral pH. The adsorption of fluoride was studied at four different temperatures, viz. 30, 40, 50 and 60°C. The kinetics of adsorption as well as adsorption isotherms at different temperatures were studied. Adsorption obeyed both Langmuir and Freundlic...
