“…Various methods used for the removal of heavy metal ions from wastewater include precipitation, ion exchange, reverse osmosis, membrane filtration, flotation, solvent extraction and coagulation [9][10][11][12][13][14]. However, these techniques are not economically viable due to higher maintenance and operational costs.…”

A new nanoporous 1,2-diaminocyclohexane-functionalized SBA-15 (Dach@SBA-15) silica sorbent was prepared. The structure and physicochemical properties of the material were characterized by elemental analysis, X-ray diffraction, transmission electron microscopy (TEM), scanning electron microscopy, FT-IR spectroscopy, nitrogen adsorption-desorption isotherms and thermogravimetric analysis. TEM image clearly showed the sheet-like structure of Dach@SBA-15. The organic functional groups were successfully grafted onto the SBA-15 surface and the ordering of the support was not affected by the chemical modification. The Dach@SBA-15was used as a sorbent for removal of Cu(II) and Ni(II) from aqueous solution. Experimental parameters like effect of pH, contact time and metal ion concentration were studied and optimized. The adsorption isotherm data fitted well to Langmuir isotherm model and the monolayer adsorption capacity values for Cu(II) was 90.09 and for Ni (II) was 84.03 mg/g at 303 K. The experimental kinetic data fitted very well to the pseudosecond-order model. The Dach@SBA-15 could be used as a sorbent for removal of Cu(II) and Ni(II) from aqueous medium.

“…To remove a metal from water, a precipitation can be effected after an oxidation or a pH change. Other technologies are flocculation [11], ion exchange [12], reverse osmosis with a membrane [13], electroremediation [14] and flotation [15,16]. In flotation, metallic M a n u s c r i p t pollutants of an aqueous phase are eliminated by addition of surfactants.…”

Polymer‐derived ceramic adsorbent for pollutant removal from water

Polymer‐derived ceramic components (SiOC, sample W) were produced from preceramic polymer mixture and a catalyst. After curing and pyrolysis, some of the samples etched by hydrofluoric acid to obtain carbonaceous SiOC (C‐rich SiOC, sample W‐HF). W and W‐HF were tested as an adsorbent material to remove both heavy‐metal ions (Cr (III), Pb (III), and Cd (II)) and cationic dyes (Methylene Blue (MB), Rhodamine B (RB), and Crystal Violet (CV)) from aqueous solutions. HF‐treated high surface area SiOC samples had quite high adsorption affinity for cationic dyes. According the Langmuir isotherm model the maximum dye uptake values were found to be around to 50 mg/g for sample W, whereas those for sample W‐HF ranged from 104 to 186 mg/g. Regeneration studies were conducted both by heat treatment and leaching, high recovery yields (always above 97%) of MB adsorption were obtained.
