Undesirable bio-adhesion of microalgae on adsorbent can influence its adsorption capacity. In this report, we fabricated a novel mussel-inspired antifouling magnetic activated carbons which derived orange peel by integrated biosorption-pyrolysis process ([email protected]), via co-functionalization of poly-dopamine (PDA) and Ag nanoparticles (AgNPs), for the recovery of uranium (VI) from simulated seawater with antimicrobial adhesion performance; this process did not require an additional reducing agent. The effect of pH, concentration, contact time, fouling test against nitzschia closterium f.minutissima (GY-H8) were studied. Compared with MACs (632.91 mg/g at pH 7.0), the calculated maximum adsorption capacity of [email protected] increased to 657.89 mg/g at pH 8.0 and showed good recyclability. These data all fitted well with the Langmuir and pseudo-second order models. The possible removal mechanism by XPS is chelation (catechol hydroxyls, amine/imine units, the metal-oxygen and carboxylic) with uranium (VI). The antifouling tests indicated that the AgNPs-modified materials displayed the antimicrobial adhesion behavior, and the viability of the microorganism was not impacted. Thereby, the direct deposition of AgNPs onto the adsorbent has shown great potential for uranium (VI) recovery with an antifouling benefit and is environmentally friendly.

微藻类对吸附剂的不良生物粘附可能会影响其吸附能力。在这份报告中，我们制造了一种新颖的贻贝类防污磁性活性炭，该炭通过集成的生物吸附-热解过程（[电子邮件保护]），通过聚多巴胺（PDA）和银纳米颗粒（AgNPs）的共官能化而衍生出橙皮，用于从模拟海水中回收具有抗菌粘附性能的铀（VI）；该过程不需要额外的还原剂。研究了pH，浓度，接触时间，结垢试验对小球藻（GY-H8）的影响。与MACs（pH 7.0时为632.91 mg / g）相比，在pH 8.0时，[电子邮件保护]的最大吸附容量计算值增加到657.89 mg / g，并显示出良好的可回收性。这些数据都非常适合Langmuir模型和伪二阶模型。XPS可能的去除机理是与铀（VI）螯合（邻苯二酚羟基，胺/亚胺单元，金属氧和羧酸）。防污测试表明，经AgNPs修饰的材料显示出抗微生物粘附行为，并且微生物的生存力没有受到影响。因此，AgNPs直接沉积在吸附剂上已显示出回收铀（VI）的巨大潜力，并且具有防污效果，并且对环境友好。并且微生物的生存力没有受到影响。因此，AgNPs直接沉积在吸附剂上已显示出回收铀（VI）的巨大潜力，并且具有防污效果，并且对环境友好。并且微生物的生存力没有受到影响。因此，AgNPs直接沉积在吸附剂上已显示出回收铀（VI）的巨大潜力，并且具有防污效果，并且对环境友好。
