“…In accordance with what several authors have previously reported (Fritzsche et al, 2011;Gan et al, 2014;García-Sánchez et al, 2010;Makris et al, 2009;Ravenscroft et al, 2005;Sahu et al, 2011;Smedley and Kinniburgh, 2002;Wey et al, 2006), this may be explained by As being frequently associated with Fe and Al compounds. Thus, higher Fe-Al content in the soil may be responsible for increase of As sorption in soil.…”

Rice and wheat husks were converted to biochars by slow pyrolysis (1 h) at 600 °C. Iron oxide rice husk hybrid biochar (RHIOB) and wheat husk hybrid biochar (WHIOB) were synthesized by copyrolysis of FeCl3-impregnated rice or wheat husks at 600 °C. These hybrid sorbents were characterized using X-ray photoelectron spectroscopy, X-ray diffraction, scanning electron microscopy (SEM), SEM–energy-dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy, transmission electron microscopy, physical parameter measurement system, and Brunauer–Emmett–Teller (BET) surface area techniques. Fe3O4 was the predominant iron oxide present with some Fe2O3. RHIOB and WHIOB rapidly chemisorbed As(III) from water (∼24% removal in first half an hour reaching up to ∼100% removal in 24 h) at surface Fe–OH functions forming monodentate Fe–OAs(OH)2 and bidentate (Fe–O)2AsOH complexes. Optimum removal occurred in the pH 7.5–8.5 range for both RHIOB and WHIOB, but excellent removal occurred from pH 3 to 10. Batch kinetic studies at various initial adsorbate–adsorbent concentrations, temperatures, and contact times gave excellent pseudo-second-order model fits. Equilibrium data were fitted to different sorption isotherm models. Fits to isotherm models (based on R 2 and χ2) on RHIOB and WHIOB followed the order: Redlich–Peterson > Toth > Sips = Koble–Corrigan > Langmuir > Freundlich = Radke–Prausnitz > Temkin and Sips = Koble–Corrigan > Toth > Redlich–Peterson > Langmuir > Temkin > Freundlich = Radke–Prausnitz, respectively. Maximum adsorption capacities, Q RHIOB 0 = 96 μg/g and Q WHIOB 0 = 111 μg/g, were obtained. No As(III) oxidation to As(V) was detected. Arsenic adsorption was endothermic. Particle diffusion was a rate-determining step at low (≤50 μg/L) concentrations, but film diffusion controls the rate at ≥100–200 μg/L. Binding interactions with RHIOB and WHIOB were established, and the mechanism was carefully discussed. RHIOB and WHIOB can successfully be used for As(III) removal in single and multicomponent systems with no significant decrease in adsorption capacity in the presence of interfering ions mainly Cl–, HCO3 –, NO3 –, SO4 2–, PO4 3–, K+, Na+, Ca2+. Simultaneous As(III) desorption and regeneration of RHIOB and WHIOB was successfully achieved. A very nominal decrease in As(III) removal capacity in four consecutive cycles demonstrates the reusability of RHIOB and WHIOB. Furthermore, these sustainable composites had good sorption efficiencies and may be removed magnetically to avoid slow filtration.

“…Fe and Al oxides are among the main factors controlling the adsorption behavior of soil for As [10,11,29], and the CaCO 3 content also affected As adsorption behavior especially in calcareous soils [16,30]. In natural soils, the As content in the five soils had a significant correlation with the Fe content ( Figure S1), which indicates that the initial As in soils were adsorbed on Fe oxides primarily.…”

“…In contrast, Zhang and Selim [20] found that the Langmuir adsorption maxima b and the Langmuir coefficient K both increased with an increasing reaction time. Sahu et al [11] studied that As(V) adsorbed on guava orchard soils and found that the adsorption maxima b had no obvious relationship with the Langmuir coefficient K.…”

“…The adsorption and desorption behavior mainly control the distribution and bioavailability of As in the soil environment. Some of the previous studies have studied the adsorption behavior of As in soil minerals [9][10][11], but the knowledge of As adsorption on saline-alkali soils is limited. It is well known that the adsorption of As in soil minerals depends on Fe, Mn and Al oxides [12,13].…”

The adsorption of arsenic plays an important role in the mobility of this toxic element in the saline-alkali soil environment. The adsorption and transport of arsenate [As(V)] in saline-alkali soils were investigated in this study. The results of kinetic experiments indicated that the rate of As(V) adsorption was initially rapid and then became slow, which were modeled well with the pseudo-second-order rate model. The adsorption isotherms were best fitted by the Langmuir and Freundlich sorption equation. The maximum adsorption capacity of soil L1was the lowest (202.8 mg/kg), and that of soil D1 was the highest (686.6 mg/kg). The difference in adsorption capacity in five soils was mainly due to the CaCO 3 content. The CaCO 3 enhanced As(V) adsorption due to the adsorption and coprecipitation of calcium with As(V). The column experiments demonstrated that the transport of As(V) in soils was detained and the degree of detainment increased with decreasing As(V) concentration.
