We report on the synthesis of boehmite aluminum oxide hydroxide particles with lamellar structure (γ-AlO(OH)) obtained from the recycling of metallic can seals, with the addition of silver nanoparticles (Ag-NPs) reduced by extract. X-ray diffractometry (XRD) confirmed the γ-phase, and scanning electron microscopy (SEM) showed the presence of Ag-NPs on the boehmite particle surface, confirming the efficiency of the synthesis to obtain the composite material. The samples were used to treat lake water, according to the Standard Methods for the Examination of Water and Wastewater. The results indicated that the elimination of total coliforms and occurred, with excellent efficiency for the Ag-boehmite sample. The tests show the possibility of reuse (5×) of the sample, as it maintained the efficiency of disinfection for . The preparation, use, and reuse of boehmite obtained from metallic waste is a case of a circular economy, focused on sustainability and green chemistry.
我们报道了通过回收金属罐密封件合成具有层状结构的勃姆石氢氧化铝颗粒（γ-AlO(OH)），并添加了由提取物还原的银纳米颗粒（Ag-NPs）。X射线衍射法（XRD）证实了γ相，扫描电子显微镜（SEM）显示在勃姆石颗粒表面存在Ag-NPs，证实了合成获得复合材料的效率。根据《水和废水检验标准方法》，将这些样品用于处理湖水。结果表明，总大肠菌群被消除，Ag-勃姆石样品的消毒效率极佳。测试表明样品具有重复使用（5次）的可能性，因为它对……保持了消毒效率。从金属废料中获得的勃姆石的制备、使用和再利用是循环经济的一个实例，重点在于可持续性和绿色化学。
