Abstract Efficient reduction of GO was performed, using cellular extracts of three algal strains. The rGO were characterized by SEM, TEM, UV-Visible spectroscopy, XRD, FTIR, Raman spectroscopy, Zeta potential and redox potentials. The rGO were then used as decontaminating agents for heavy metals (Cu and Pb), in waste water. GO reduced via JSC-1 have removed up to 93% Cu and 82% Pb (adsorption capacity of 93 mg g−1 and 82 mg g−1, respectively), by 211-9a have removed 74% (74 mg g−1) Cu and 89% (89 mg g−1) Pb, while by 211-11n have adsorbed 91% (91 mg g−1) Cu and 95% Pb (95 mg g−1), within 30 min.

基于藻类提取物的具有增强重金属吸附能力的还原氧化石墨烯 (rGO) 的生物合成

摘要 使用三种藻类菌株的细胞提取物进行了 GO 的有效还原。通过SEM、TEM、紫外-可见光谱、XRD、FTIR、拉曼光谱、Zeta电位和氧化还原电位对rGO进行表征。然后将 rGO 用作废水中重金属（Cu 和 Pb）的净化剂。通过 JSC-1 还原的 GO 去除了高达 93% 的 Cu 和 82% 的 Pb（吸附容量分别为 93 mg g-1 和 82 mg g-1），到 211-9a 已经去除了 74%（74 mg g-1 ) Cu 和 89% (89 mg g-1) Pb，而到 211-11n 在 30 分钟内吸附了 91% (91 mg g-1) Cu 和 95% Pb (95 mg g-1)。
