“…2b). This adsorption capacity was 1.46-2.32 times that of Amberlite ion exchange resins such as IRN77, SKN1 and IR120 [2,32], and was 1.37-1.94 times of that of various low-cost sorbents including biomass, clay minerals and industrial wastes as reported previously [9][10][11][12][13][14].…”

“…Hence, the use of various low-cost sorbents for removing cobalt is a subject of considerable interest in today's society. Such materials include hemp fibers, sunflower biomass, almond green hulls, mangosteen shells, zeolites, Al-pillared clay, sepiolite, industrial wastes, etc [9][10][11][12][13][14]. It should be noted that the sorption capacity of these low-cost sorbents for cobalt species are rather low (<80 mg g À1 ) and the overall process is strongly dependent on the pH of the solution.…”

“…Based on the above idea, in an earlier study we have prepared a kind of sorbent by using mangosteen peel as the raw material (Huang et al 2013), which is rich of polyphenolic compounds such as anthocyanin, resveratrol etc. (Naczk et al 2011;Tao et al 2009;Wang et al 2012;Zadernowski et al 2009;Zein et al 2010), through modification by alkaline soaking, i.e., saponification process. The obtained saponified mangosteen peel gel showed quite excellent adsorption properties for Cr(VI) removal with high selectivity and large adsorption capacity.…”

In present study the potential of a new biosorbent obtained from mangosteen peel was investigated for the removal of hexavalent chromium and trivalent chromium from the aqueous solutions. The biosorbent was modified by using concentrated sulphuric acid as the crosslinking reagent. Various batch experiments were carried out testing different values of several parameters such as pH, contact time, adsorbent dosages, and metal ion concentration to identify the optimum conditions. The effect of these parameters on the adsorption capacity and selectivity was studied. Results showed that optimum pH for hexavalent chromium adsorption was 3.0 and adsorption equilibrium was attained in 120 min. The adsorption data were found to fit Langmuir model and pseudo-secondorder equation. The adsorption mechanism for hexavalent chromium was found to be a complex process involving esterification, reduction and ion exchange, while cation exchange is the main route for trivalent chromium adsorption. From the above results, the crosslinked mangosteen peel gel appears to be a potential low-cost and effective adsorbent for hexavalent chromium and trivalent chromium removal from the waste water.

“…Therefore, their efficient removal from water is of great importance. [1][2][3] Adsorption is one of the most effective and simplest approaches that has been developed for this purpose. 4,5 In recent years, hierarchical structures with hollow interiors are of special research interest in the fields of catalysis, adsorption, chemical reactors, sensors, photonic crystals and drug delivery, due to their lower density, higher specific surface area and better permeation compared with the solid and/or bulk counterparts.…”

Cost effective and shape controlled approach to synthesize hierarchically assembled NiO nanoflakes for the removal of toxic heavy metal ions in aqueous solution

Hierarchical mesoporous NiO nanoflakes (NiOs) have been synthesized in high yield via a simple, economical and environmentally friendly hydrothermal route. The as-prepared NiOs were characterized by powder X-ray diffraction (PXRD), scanning electronic microscopy (SEM), transmission electron microscopy (TEM), selected area electron diffraction patterns (SAED), X-ray energy dispersive spectroscopy (EDS) and nitrogen adsorptiondesorption techniques (Brunauer-Emmett-Teller, BET). Adsorption of heavy metal ions onto the as-prepared sample from aqueous solutions was investigated using differential pulse anodic stripping voltametry (DPASV) technique and discussed. The product possesses a BET surface area of 69.27 m 2 g −1 . It is found that NiOs exhibited the excellent performance for the removal of Hg(II), Pb(II) and Cd(II) from aqueous solution. The equilibrium adsorption data of Hg(II), Pb(II) and Cd(II) on the as-prepared NiOs were analyzed by Langmuir and Freundlich models, suggesting that the Langmuir model provides the better correlation of the experimental data. The adsorption capacities for removal of Hg(II), Pb(II) andCd(II) were determined using the Langmuir equation and found to be 1324.5, 1428.9 and 1428.5 mg g −1 , respectively. Adsorption kinetics of all the metal ions followed pseudo second-order model. Moreover, NiOs can be recycled by simple acid treatment, which could retain the high removal efficiency in three successive cycles. This study suggests that nanoflakes could be explored as a new adsorbent with high efficiency and recyclability for removing heavy metal ions from aqueous solution.
