In response to the demand for Sb(Ⅴ) pollution remediation in groundwater of mining areas, and to overcome the low adsorption capacity of conventional layered double hydroxides (LDHs), a urea-assisted hydrothermal method was adopted to modify MgAl-LDHs via Ni/Co co-doping. The results show that a nanosheet material with a Ni/Co molar ratio of 2∶1 (denoted as N2C1) was prepared and applied to adsorb Sb(Ⅴ). At room temperature, N2C1 exhibited a maximum theoretical Sb(Ⅴ) adsorption capacity of 60.04 mg/g, while the actual adsorption capacity was significantly enhanced from 11.6 mg/g for pristine LDHs to 41.7 mg/g. The adsorption behavior conformed to the Freundlich isotherm model and the pseudo-second-order kinetic model, with rapid uptake occurring within the first 20 min and equilibrium being reached at approximately 120 min. Column tests and coexisting ion interference experiments demonstrate that the material possesses favorable dynamic removal performance and anti-interference capability in complex groundwater environments. Environmental compatibility assessment indicates that the leaching concentrations of Ni, Co, and Al remained below the detection limits within the pH range of 4-12, with only a minor release of Mg observed under acidic conditions, suggesting a low environmental risk. Combined Zeta potential, FT-IR, and XPS analyses confirm that the enhanced Sb(Ⅴ) removal performance was attributed to the synergistic effects of strengthened electrostatic attraction, enhanced surface complexation, and interlayer anion exchange. This study provides a theoretical basis and material support for the application of Ni/Co co-doped LDHs in the in situ remediation of antimony-contaminated groundwater in mining areas.

为满足矿区地下水中Sb(Ⅴ)污染治理需求,克服传统水滑石吸附容量低等问题,研究采用尿素水热法,通过镍钴共掺杂对镁铝层状双金属氢氧化物(MgAl-LDHs)进行改性,制备了Ni/Co物质的量比为2∶1的纳米片材料(N2C1)并用于吸附Sb(Ⅴ)。结果表明:常温下,N2C1对Sb(Ⅴ)的最大理论吸附容量达60.04 mg/g,实际吸附容量由传统LDH的11.6 mg/g显著提升至41.7 mg/g;吸附行为符合Freundlich等温模型和准二级动力学模型,在前20 min内迅速升高,于120 min左右达到平衡。柱试验与共存离子干扰试验结果表明:该材料在复杂地下水环境中具有良好的动态去除性能和抗干扰能力。环境友好性评估显示,在pH=4~12范围内,Ni、Co、Al溶出量低于检测限,仅Mg在酸性条件下有少量释放,环境风险较低。结合Zeta电位、FT-IR及XPS分析,确认Sb(Ⅴ)去除性能的提升源于静电吸引增强、表面配合作用强化及层间阴离子交换的协同效应。研究结果可为镍钴共掺杂水滑石在矿区含锑地下水原位修复中的应用提供理论依据与材料支撑。

为满足矿区地下水中Sb(Ⅴ)污染治理需求,克服传统水滑石吸附容量低等问题,研究采用尿素水热法,通过镍钴共掺杂对镁铝层状双金属氢氧化物(MgAl-LDHs)进行改性,制备了Ni/Co物质的量比为2∶1的纳米片材料(N2C1)并用于吸附Sb(Ⅴ)。结果表明:常温下,N2C1对Sb(Ⅴ)的最大理论吸附容量达60.04 mg/g,实际吸附容量由传统LDH的11.6 mg/g显著提升至41.7 mg/g;吸附行为符合Freundlich等温模型和准二级动力学模型,在前20 min内迅速升高,于120 min左右达到平衡。柱试验与共存离子干扰试验结果表明:该材料在复杂地下水环境中具有良好的动态去除性能和抗干扰能力。环境友好性评估显示,在pH=4~12范围内,Ni、Co、Al溶出量低于检测限,仅Mg在酸性条件下有少量释放,环境风险较低。结合Zeta电位、FT-IR及XPS分析,确认Sb(Ⅴ)去除性能的提升源于静电吸引增强、表面配合作用强化及层间阴离子交换的协同效应。研究结果可为镍钴共掺杂水滑石在矿区含锑地下水原位修复中的应用提供理论依据与材料支撑。

In response to the demand for Sb(Ⅴ) pollution remediation in groundwater of mining areas, and to overcome the low adsorption capacity of conventional layered double hydroxides (LDHs), a urea-assisted hydrothermal method was adopted to modify MgAl-LDHs via Ni/Co co-doping. The results show that a nanosheet material with a Ni/Co molar ratio of 2∶1 (denoted as N2C1) was prepared and applied to adsorb Sb(Ⅴ). At room temperature, N2C1 exhibited a maximum theoretical Sb(Ⅴ) adsorption capacity of 60.04 mg/g, while the actual adsorption capacity was significantly enhanced from 11.6 mg/g for pristine LDHs to 41.7 mg/g. The adsorption behavior conformed to the Freundlich isotherm model and the pseudo-second-order kinetic model, with rapid uptake occurring within the first 20 min and equilibrium being reached at approximately 120 min. Column tests and coexisting ion interference experiments demonstrate that the material possesses favorable dynamic removal performance and anti-interference capability in complex groundwater environments. Environmental compatibility assessment indicates that the leaching concentrations of Ni, Co, and Al remained below the detection limits within the pH range of 4-12, with only a minor release of Mg observed under acidic conditions, suggesting a low environmental risk. Combined Zeta potential, FT-IR, and XPS analyses confirm that the enhanced Sb(Ⅴ) removal performance was attributed to the synergistic effects of strengthened electrostatic attraction, enhanced surface complexation, and interlayer anion exchange. This study provides a theoretical basis and material support for the application of Ni/Co co-doped LDHs in the in situ remediation of antimony-contaminated groundwater in mining areas.
