“…In contrast, the ions with high biosorption such as Cd and Ni may have penetrated the biosorbent surface through the pores present. Similar findings were reported in our earlier work with AP and CP beads (Singh et al 2019a(Singh et al , 2019b.…”

“…In fact, neutral pH has been reported as optimum for Cu biosorption by Pinus sawdust (Semerjian 2018). Overall, the results for Cu, Hg, Pb and Ni biosorption by BP, OP and PP beads are similar to our results for CP bead biosorption of these ions from an identical cocktail solution (Singh et al 2019b).…”

“…4). Similar behaviour of Cu ions was observed with CP bead in our previous work, where the ion had not reached equilibrium within 72 h (Singh et al 2019b). This suggests that surfaces of CP and PP beads were not suitable for the competitive binding of Cu relative to the other ions.…”

“…Biosorbent beads were prepared from BP, OP and PP according to the methods published in our earlier work with apple and cucumber peel beads (AP and CP, respectively) (Singh et al 2019a(Singh et al , 2019b. BP, OP and PP were washed once with hot water, twice with tap water and twice with deionised distilled water, dried, pulverised and sieved to particle size < 240 µm.…”

Banana, orange and potato peels (BP, OP and PP, respectively) were immobilised to produce biosorbent beads that were employed for the biosorption of heavy metals from a cocktail solution containing As(V), Cd(II), Cr(VI), Cu(II), Hg(II) and Ni(II) ions. Drinking water conditions were maintained with neutral initial pH and low concentration of the ions. Batch experiments were performed for evaluating the effect of pH in the drinking water range (6.5–8.5). Results showed a significant increase in the biosorption capacity of the beads with respective to the uptake of As and Pb, whereas it decreased significantly for Cd, Cu, Hg and Ni ions at basic pH values. Approximate equilibrium biosorption of Cd, Cu, Hg and Ni was 89–92%, 79–87%, 84% and 71–80% by BP, OP and PP beads. The physisorption-based PFO model was the most suitable for the ions with biosorption capacities closer to the experimental values. BP and OP beads had better biosorption efficiencies relative to PP bead due to the higher surface heterogeneity observed by scanning electron microscopy coupled with energy-dispersive spectroscopy. An increase in the biosorbent concentration from one to ten BP beads significantly increased the biosorption percentage of the ions. The biosorption capacities of Cd, Hg and Ni uptake by one BP bead from a 1 mgL−1 cocktail solution were 3.4 ± 0.0, 5.3 ± 0.1 and 3.0 ± 0.0 mgg−1, respectively. Thus, BP beads were the most effective than for the simultaneous removal of heavy metals from drinking water.

“…The magnetic Co/SiO 2 nanoparticles were separated after adsorption process with the help of a magnet and showed reusability up to three cycles without much loss in adsorption efficiency. Beads of cucumber peel were used to remove heavy metals from drinking water [95]. Deionized laboratory water was spiked with seven toxic ions: arsenic, cadmium, chromium, copper, mercury, lead, and nickel at concentrations of 0.1 mg/L and kinetic studies were performed over 72 h. Results indicated that different ions contained in a multi-ion solution were biosorbed by different mechanisms and at different rates.…”

Adsorption Processing for the Removal of Toxic Hg(II) from Liquid Effluents: Advances in the 2019 Year

Mercury is a toxic metal, thus, it is an element which has more and more restrictions in its uses, but despite the above, the removal of this metal, from whatever the form in which it is encountered (zero valent metal, inorganic, or organic compounds), and from different sources, is of a widespread interest. In the case of Hg(II), or Hg2+, the investigations about the treatment of Hg(II)-bearing liquid effluents (real or in most cases synthetic solutions) appear not to end, and from the various separation technologies, adsorption is the most popular among researchers. In this topic, and in the 2019 year, more than 100 publications had been devoted to this field: Hg(II)-removal-adsorption. This work examined all of them.
