“…Furthermore, from the perspective of chemical balance, a higher temperature might be beneficial for the chelating agent (EDTA) to adsorb more metal ions . Also, a comparison of Cr(VI) and Ni(II) with maximum adsorption capacities using EDTA‐DW with other adsorbents was made, as presented in Table .…”

The adsorption of Cr(VI) and Ni(II) using ethylenediaminetetraacetic acidmodified diatomite waste (EDTA-DW) as an adsorbent in single and binary systems was investigated. The EDTA-DW was characterized using various analytical techniques, including Fourier transform infrared spectroscopy, thermogravimetric analysis, Brunauer-Emmett-Teller measurements, X-ray diffraction, scanning electron microscopy and energy-dispersive spectrometry.The adsorption experiment was conducted by varying pH, adsorbent dosage, initial concentration and temperature. In the single system, the sorption data for Cr(VI) fitted the Langmuir isotherm, but the Ni(II) adsorption data fitted well the Freundlich isotherm. The maximum sorption capacity of Cr(VI) and Ni(II) was 2.9 mg g −1 at pH = 3 and 3.64 mg g −1 at pH = 8, respectively. The kinetic data for both Cr(VI) and Ni(II) followed well the pseudo-second-order kinetic model in single and binary systems. Meanwhile, the extended Langmuir and extended Freundlich multicomponent isotherm models were found to fit the competitive adsorption data for Cr(VI) and Ni(II). In addition, in the binary system, the existence of Ni(II) hindered the adsorption of Cr(VI), but the presence of Cr(VI) enhanced the removal of Ni(II). This study provides some realistic and valid data about the usage of modified diatomite waste for the removal of metal ions.

“…It shows that the chemisorption of As(V) ions was the ratedetermining step of the adsorption process. This process contains the chemical interaction between As(V) ions and polar groups on the adsorbent, such as ion exchange and chelating reaction (Zhou et al, 2016;Yang et al, 2016). For 50 °C, 40 °C, 30 °C the pseudo second order rate constant k2 were calculated as 0.034 g/mg.min, 0.033 g/mg.min and 0.030 g/mg.min.…”

“…The trace elements like lead (Pb), cadmium (Cd), zinc (Zn), mercury (Hg), arsenic (As), silver (Ag), chromium (Cr), copper (Cu), and iron (Fe) can accumulate unnoticed to toxic levels and cause many diseases and even death (Duruibe et al, 2007;Yang et al, 2016). Arsenic is a hazardous, toxic and carcinogenic metalloid which can get into drinking water, underground water, etc.…”

“…In recent years, studies have been focused on alternative adsorbents which are derived from industrial wastes. Industrial wastes like rice husk, peanut shells, fly ash, coconut husk, waste coffee and tea has been recycled to low-cost biosorbents (Cheraghi et al, 2015;Yang et al, 2016;Uddin et al, 2009). Coal-fired thermal power plants have led to an increase in the occurrence of many solid wastes such as fly ash and bottom ash (Fonteboa et al, 2017;Noh & Son, 2017).…”

Industrial development brings waste problem which is a challenge for both human health and ecological cycle. Arsenic is a toxic and carcinogenic heavy metal that should be removed from drinking or waste water. In this study, an industrial waste of bottom ash was used as an adsorbent to remove As (V). To find an appropriate adsorption conditions, the adsorption temperatures and contact time were varied between 30 °C-50 °C and 5-180 min, respectively. The experimental results were fitted to the Langmuir and Freundlich isotherms. The highest values of n and KF for Freundlich isotherm were obtained for 30 °C and calculated as 0.432 and 0.006, respectively. According to kinetic studies, the kinetics of these experiments could be explained by pseudo-second order kinetic model, and the pseudo-second order rate constant was calculated as 0.034 g/mg.min, 0.033 g/mg.min and 0.030 g/mg.min for 30 °C, 40 °C and 50 °C, respectively. According to experimental results, bottom ash can be used for removal of As (V) from water sources.UDC Classification: 66.03; DOI: http://dx

The bamboo charcoal modified with Cu2+ and 3‐aminopropyl trimethoxy silane (BC‐Cu/Si‐NH2) was synthesized and characterized by X‐ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, energy dispersive spectroscopy, and surface acid–base potentiometric titration. The adsorption for acid fuchsin (AF) dyes onto BC‐Cu/Si‐NH2 was investigated. Moreover, response surface methodology was performed to optimize the process parameters including pH, initial dye concentration, adsorbent dosage, and temperature. The results presented that the adsorption process was mainly influenced by initial AF concentration and adsorbent dosage. Isotherm studies revealed that the adsorption data fitted well with the Sips model and Dubinin–Radushkevich (D–R) model, which indicated the monolayer, homogeneous, and physical nature of the adsorption process. The maximum adsorption capacity calculated from D–R model could approach approximately to 14.91 mg g−1 at 40 °C, and the maximum adsorption capacity of Sips reached to 10.77 mg g−1 at 40 °C. The kinetic experimental data matched well with Spahn and Schlunder model as well as pseudo‐second‐order model. In addition, intraparticle diffusion was not the only rate‐controlling step of adsorption process. Thermodynamic parameters revealed the feasibility, spontaneity, and endothermic nature of adsorption. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47728.
