The authors of this paper use an original method diatomaceous earth fractionation, which allows for obtaining a filler with specific particle size distribution. makes it possible to separate small, disintegrated and broken diatom frustules from those maintained their form in earth. study covers range tests conducted prove that such separated diatomic fraction (3–30 µm) shows features different ...

The stable of natural diatomite supported by potassium hydroxide (KOH) as catalysts were synthesized for biodiesel production. A heterogeneous base catalyst prepared impregnating KOH onto was also used to synthesize from palm oil. All samples have been thoroughly characterized Wavelength Dispersive X-ray Fluorescence (WDXRF), diffraction (XRD), N2 adsorption/desorption, Scanning electron micros...

The progress of the textile industry has led to a severe increase in discharge colored effluents, polluted with dyes and metal ions (non-biodegradable, carcinogenic humans environmental hazards). implementation effective methodologies materials for treatment wastewater become an urgent requirement. present work describes application two samples mineral materials—Ghidirim diatomite modified diat...

The possibility of transforming a diatomite-rich waste from the brewing industry into synthetic zeolites has been investigated. After precalcination at 550 °C to eliminate retained organic matter, clean diatomite (Dt; with Si/Al molar ratio 17.4), was hydrothermally treated for 24 h continuous stirring in 3M NaOH solution 80 °C. results mineralogical characterization by X-ray diffraction Rietve...
