Description
| - The present paper deals with influence of oxalic acid on vermiculite structure. The particles size less than 0.2 mm of natural powdered vermiculite from Brazil was used. Powdered natural vermiculite sample were treated for 60 and 180 minutes in water solution with oxalic acid at define temperature. Using the same condition the vermiculite particles was treated in deionised water. The cations Ca, Mg, K, Si and Al concentrations in filtrate were determined by the spectroscopy methods. The changes of vermiculite structure using X-ray diffraction analysis, infra-red spectroscopy and scanning electron microscopy with EDS detector were studied. Sample particle size and specific surface area were detected using laser granulometr. It was found that the oxalic acid solution has an impact on vermiculite structure and size of particle. Significant influence has an experimental temperature.
