This study used MIL-88A-(Fe)/cotton (MC) as an adsorbent to effectively remove vanadium-(V) from simulated vanadium-contaminated groundwater, demonstrating excellent adsorption performance and specificity in a wide pH range. It also met the vanadium content restriction required in China's drinking water sources.
A suitable adsorbent is essential in the process of removing hazardous vanadium-(V) from actual groundwater. In this work, MIL-88A-(Fe)/cotton (MC) was employed to eliminate V-(V) from simulated vanadium-contaminated groundwater. The findings demonstrated that MC exhibited an exceptional performance in removing V-(V), displaying a maximum adsorption capacity of 218.71 mg g(-1). MC exhibits great promise as an adsorbent for V-(V) elimination in an extensive pH range spanning 3 to 11. Even in the presence of high levels of competing ions such as Cl-, NO3 -, and SO4 (2-), MC demonstrated remarkable specificity in adsorbing V-(V). The results of column experiments and co-occurring ions influence tests indicate that MC is a potential candidate for effectively treating actual vanadium-contaminated groundwater. The effluent could meet the vanadium content restriction of 50 mu g L-1 required in China's drinking water sources. Regeneration of MC can be performed easily without experiencing significant capacity loss. The results obtained from this research indicate the promising potential of MC in mitigating vanadium pollution.
