Abstract The calcium silicate hydrate (CSH) was synthesized from the solid waste residue (SWR) of Alum Factory, and used for phosphate abatement an aqueous solution. Fixed-bed column adsorption experiments were conducted at different flow rates (5, 7.5, 10 mL/min) bed depths (6, 9, 12 cm) initial pH concentrations 5 5.5 mg/L, respectively. breakthrough curve analysis developed tabulated effects...

Activated carbons are universal adsorbents that can be obtained from a wide variety of raw materials, and have been found to be very effective for mercury removal from water. This contribution presents a comparative adsorption in column study of activated carbons obtained by physical activation of carbonized eucalyptus wood with water vapour, as adsorbents of mercury in liquid phase. Two sampl...

Highly ordered mesoporous MCM-41silica with hexagonal structure was synthesized using extracted amorphous silica from sedge (Carex riparia) ash. Obtained mesoporous materials functionalized by 3-(Aminopropyl) trimethoxysilane (APTMS) and their structures characterized by means of X-ray diffraction (XRD), nitrogen adsorption-desorption, thermogravimetric analysis (TGA) and Fourier transform infr...

Nanoparticles of iron precipitates produced by a microbial consortium are suitable adsorbent for metal removal from electroplating industry wastewaters. Biogenic were utilized as adsorbents chromate and zinc in batch conditions. Furthermore, the embedded alginate beads fixed-bed columns, their performance was evaluated continuous system varying different operational parameters such flow rate, b...
