| 7 | Rapid Degrading Carbamazepine in a Novel Advanced Oxidation Process of Bisulfite Activated by Lithium Cobaltate Recovered from Spent Lithium-ion Battery显示文摘Maximizing the sustainable recycling of spent lithium-ion batteries(LIBs)shows economic and environmental significance.This study recovered lithium cobaltate(LiCoO_(2),LCO)from spent LIBs cathode powder.The recovered LCO was then combined with NaHSO_(3)to remove refractory organic pollutants of carbamazepine(CBZ)in water.The degradation of CBZ reached 80.0%within 60 min,by 1O_(2),SO_(4),OH and O_(2)^(-)generated in the LCO/NaHSO_(3)reaction.The electron transfer between Co(III)and Co(II)was beneficial to the generation of free radicals.The LCO/NaHSO_(3)degraded CBZ effectively in both secondary outlet water and tap water.However,high concentrations of inorganic ions(Cl^(−),HCO_(3)^(-),HPO_(4)^(2-),SO_(2)−4,NO_(3)^(-))and natural organic matter(humic acid,HA)could inhibit the degradation of CBZ.After three cycles,the stability of the LCO/NaHSO_(3)system was demonstrated by the maintained high efficiency in the degradation of CBZ.The obtained data indicate that the LCO/NaHSO_(3)system holds great application potential in the field of advanced oxidation degradation of pollutants. | Yan Jiali Yang Kaiying Wang Xi Zhai Jinli Zhu Wenjie Yang Daoli Luo Yongming Gao Xiaoya | 2024 | Chemical Research in Chinese Universities2024，40，1： | 0 |
