“…Furthermore, the amount of phosphorus dissolved in HAP + FHSb(III) immobilized soil was lower than that in HAPSb(III) immobilized soil throughout the incubation period, suggesting that the phosphorus dissolved from the hydroxyapatite would be sorbed on the ferrihydrite in the combined application. Such phosphorus sorption by the ferrihydrite competes with antimony sorption, which leads to enhanced antimony dissolution (Nakamaru et al 2006). However, in this study, the antimony mobility was not enhanced in FH-Sb(III) and HAP + FHSb(III) immobilized soils, although the antimony(III) sorbed on the materials was oxidized.…”

The combined application of hydroxyapatite and ferrihydrite can simultaneously immobilize lead and antimony(V) in oxic soil. However, this has not been demonstrated for antimony(III). In this study, antimony(III) sorption experiments in solution and dissolution experiments in oxic soil were conducted using the combined application of hydroxyapatite and ferrihydrite to elucidate the contribution of the materials to antimony(III) sorption and to evaluate the amount of antimony dissolved from the antimony(III)-sorbed materials by the change in redox state in oxic soil. All the antimony(III) in 50 mg l −1 solution at pH 5 was sorbed on the combined materials without oxidation. The contribution of ferrihydrite and hydroxyapatite on antimony(III) sorption was 92.6 and 7.4 %, respectively. The antimony(III) sorbed on the combined materials was not oxidized within 7 days of incubation period in oxic soil. However, after 90 days of incubation period, all the antimony(III) was oxidized to antimony(V). The percentage of antimony dissolution from the simulativeimmobilized soil with the antimony(III)-sorbed combined material was constant at less than 1 % during incubation periods. Therefore, no enhancement in the antimony soil mobility in the soil with the combined application was observed, although antimony(III) was oxidized. These results suggest that the combined application of hydroxyapatite and ferrihydrite could immobilize antimony(III) without re-dissolving antimony through oxidation. Thus, the combined application would be applicable to lead-and antimonycontaminated soil.

“…Flynn et al (2003) also have shown that despite of very high level of soil antimony at mine and smelter sites, antimony bioavailability is low. Antimony has been observed to have relatively low mobility in soils (Lintschinger et al 1998;Hammel et al 2000;Nakamaru et al 2006). The studies on the culturable soil microbial community are based on cultivation methods and the major problem of the cultivation-based analysis is that only a small fraction of microorganisms is cultivatable.…”

The effects of both combined and single pollution of antimony (Sb) and arsenic (As) in different concentrations on culturable soil microbial populations and enzyme activities were studied under laboratory conditions. Joint effects of both Sb and As were different from that of Sb or As alone. The inhibition rate of culturable soil microbial populations under Sb and As pollution followed the order: bacterial > fungi > actinomycetes. There existed antagonistic inhibiting effect on urease and acid phophatase and synergistic inhibiting effect on protease under the combined pollution of Sb (III) and As (III). Only urease appeared to be the most sensitive indicator under Sb (V) and As (V) pollution, and there existed antagonistic inhibiting effect on acid phophatase and synergistic inhibiting effect on urease and protease under Sb (V) and As (V) combined pollution at most time. In this study, we also confirmed that the trivalent states of Sb and As were more toxic to all the microbes tested and more inhibitory on microbial enzyme activities then their pentavalent counterparts. The results also suggest that not only the application rate of the two metalloids but also the chemical form of metalloids should be considered while assessing the effect of metalloid on culturable microbial populations and enzyme activities. Urease and acid phosphatase can be used as potential biomarkers to evaluate the intensity of Sb (III) and As (III) stress.

“…Studies on pure mineral phases often revealed that Sb adsorption was initially fast followed by a slow kinetic process extended for several days (Leuz and Johnson, 2005;Leuz et al, 2006;McComb et al, 2007;Xi et al, 2011;Ilgen and Trainor, 2012). The study of Sb(V) sorption on Japanese soils conducted by Nakamaru et al (2006) concluded that 7-d reaction time was sufficient to achieve equilibrium of Sb sorption. Martinez-Llado et al (2011) studied Sb(V) sorption on calcareous soils and found the sorption kinetics was relatively slow with equilibrium reached after days.…”

“…Adsorption-desorption on soil matrix and precipitationdissolution of Sb minerals are believed to be the primary processes controlling the mobility of Sb in soils. The soil-solution distribution coefficients (K d ) of Sb measured for 110 Japanese agricultural soil samples ranged from 1 to 2100 L kg À1 and exhibited a decreasing trend with increasing pH and increasing phosphate concentration (Nakamaru et al, 2006). It appears that both Sb(III) and Sb(V) bind strongly to hydroxides of Fe, Al, and Mn and only weakly to clay minerals (Leuz and Johnson, 2005;Leuz et al, 2006).…”

h i g h l i g h t sSb(V) sorption on soils were timedependent and irreversible. Retention mechanisms were different for acidic red soil and calcareous soil. Sb(V) transport in soils dominated by non-equilibrium reactions. Kinetic reversible-irreversible MRM formulation well described experiment results. Antimonate [Sb(V)] adsorption-desorption and transport in an acidic red soil (Yingtan) and a calcareous soil (Huanjiang) was investigated using kinetic batch and miscible displacement experiments. Different formulations of a multi-reaction model (MRM) were evaluated for their capabilities of describing the retention and transport mechanisms of Sb(V) in soils. The experimental results showed that adsorption of Sb(V) by two soils was kinetically controlled and largely irreversible. The Sb(V) adsorption capacity and kinetic rate of the acidic red soil was much higher than that of the calcareous soil. The asymmetrical breakthrough curves indicated the strong dominance of non-equilibrium retention of Sb(V). A four step sequential extraction procedure provided evidence that majority of applied Sb(V) was irreversibly retained. A formulation of MRM with two kinetic sorption sites (reversible and irreversible) successfully described Sb(V) adsorption-desorption data. The use of kinetic batch rate coefficients for predictions of breakthrough curves (BTCs) underestimated Sb(V) retention and overestimated its mobility. In an inverse mode with optimized rate coefficients, the MRM formulation was capable of simulating Sb(V) transport in soil columns.
