“…In parallel, it is interesting to consider species such as Hg 2+ that have good affinities for both the carbon surface and the hydroxyapatite layer. The retention ability of activated carbons towards mercury in conditions comparable to this work was reported to range between 0.01 mg g -1 and 100 mg g -1 [38,39]. However, the highest values are obtained for materials with much higher specific surface area (1100 m 2 g -1 ,…”

Novel hierarchically-organized magnetic microspheres have been successfully developed that consist of an aqueous hollow core, a magnetic porous Fe 3 O 4 -carbon layer and a well-define hydroxyapatite (HAp) shell. The hollow magnetic carbon microspheres were prepared by ultrasonic spray pyrolysis and coated with HAp using a biomimetic approach. The resulting powders exhibit micro-and meso-porosity. The removal capacity of the composite spheres towards an antibiotic (ampicilin), a rare-earth ion (La 3+ ) and two heavy metals (Hg 2+ and Pb 2+ ) has been studied and compared with that of the individual components. The dual organic-inorganic affinity of the magnetic HAp/carbon conjugates was demonstrated, with synergetic effects being evidenced for heavy metal removal enlightening their potentialities in wastewater treatment.

“…Activated carbons are universal adsorbents that can be obtained from a wide variety of raw materials including wastes of industrial activities [9][10][11][12][13] . Activated carbons have been found to be a very effective alternative for mercury removal from water [14][15][16][17][18][19][20][21] . Adsorption in liquid phase is a complex phenomenon because both, solute and solvent, compete for the solid surface.…”

Adsorption of mercury (II) from liquid solutions using modified activated carbons

Mercury is one of the most toxic metals present in the environment. Adsorption has been proposed among the technologies for mercury abatement. Activated carbons are universal adsorbents which have been found to be a very effective alternative for mercury removal from water. The effectiveness with which a contaminant is adsorbed by the solid surface depends, among other factors, on the charge of the chemical species in which the contaminant is in solution and on the net charge of the adsorbent surface which depend on the pH of the adsorption system. In this work, activated carbon from carbonized eucalyptus wood was used as adsorbent. Two sulphurization treatments by impregnation with sulphuric acid and with carbon disulphide, have been carried out to improve the adsorption capacity for mercury entrapment. Batch adsorption tests at different temperatures and pH of the solution were carried out. The influence of the textural properties, surface chemistry and operation conditions on the adsorption capacity, is discussed.

“…The final concentration of Hg (II) ions was determined employing an atomic fluorescence spectrometer (AFS, AI3200, Auror). The amount of uptake capacity at equilibrium was calculated by Equation (1). The experimental data were fitted with Langmuir model and the Langmuir equation was formulated as Equation (2).…”

“…Mercury-containing wastewater, generated from combustion of fossil fuels, chlorine-alkali industry, pulp and paper industry and PVC industry, is highly toxic and harmful [1]. Among treatment approaches, adsorption is an effective technology for removal of Hg (II) ions from wastewater or other aqueous solutions [2][3][4].…”

Abstract. Removal of Hg (II) ions from industrial wastewater is important for the water treatment, and adsorption is an efficient treatment process. Activated carbon (AC) was modified with melamine, which introduced nitrogen-containing functional groups onto AC surface. Original AC and melamine modified activated carbon (ACM) were characterized by elemental analysis, N2 adsorption-desorption, determination of the pH of the point of zero charge (pHpzc) and X-ray photoelectron spectroscopy (XPS) and their performance in the adsorption of Hg(II) ions was investigated. Langmuir model fitted the experimental data of equilibrium isotherms well. ACM showed the higher Hg (II) ions adsorption capacity, increasing more than more than 1.8 times compared to the original one. Moreover, ACM showed a wider pH range for the maximum adsorption than the parent AC.
