In this study, batch and spectroscopic approaches were used to explore the sorption of Pb(II) on micas (i.e., muscovite, biotite and phlogopite) in the presence of Trichoderma viride (T. viride). Batch sorption showed that ion exchange, outer-sphere complexes (OSCs) and inner-sphere complexes (ISCs) contributed to Pb(II) sorption on biotite and phlogopite in the pH range of 2.0–7.4, whereas the ISCs were predominant for Pb(II) sorption on muscovite. X-ray diffraction and Fourier transform infrared (FT-IR) analyses have confirmed the changes of structure and surface properties of micas after co-culturing with T. viride, which could improve the sorption capacity of micas to Pb(II). Scanning electron microscopy revealed the bio-mineralization of Pb(II) on T. viride and mica–T. viride composites forming lead phosphates. Furthermore, FT-IR analysis showed that the groups of Si−OH, Al−OH from micas, and carboxyl, phosphate and amino groups from T. viride were synergistically contributing to Pb(II) sorption on mica–T. viride composite. X-ray photoelectron spectroscopy further confirmed that both OSCs and ISCs formed for Pb(II) sorption on micas; however, in the case of mica–T. viride composites, the synergistic effects of T. viride and micas were contributing to Pb(II) sorption through forming the ISCs and biomineralization.

在这项研究中，批处理和光谱方法用于探索的Pb（II）的对中的存在云母（即，白云母，黑云母和金云母）吸附绿色木霉（绿色木霉）。分批吸附表明，离子交换，外球络合物（OSCs）和内球络合物（ISCs）有助于在pH范围为2.0-7.4的黑云母和金云母上吸附Pb（II），而ISCs以Pb（ II）在白云母上的吸附。X射线衍射和Fourier变换红外光谱（FT-IR）分析已确认的云母的结构和表面特性后，用共培养的变化绿色木霉，这可能提高云母的吸附容量对Pb（II）。扫描电子显微镜显示Pb（II）的生物矿化T. viride和云母-T . viride复合材料形成磷酸铅。此外，FT-IR分析表明，来自云母的Si-OH，Al-OH和来自T. viride的羧基，磷酸根和氨基基团协同作用促进了Pb（II）在云母– T上的吸附。维里德复合材料。X射线光电子能谱进一步证实了OSC和ISC都是由于云母上的Pb（II）吸附而形成的。然而，在云母的情况下绿色木霉复合物，的协同效应绿色木霉和云母是对Pb贡献（II）吸附通过形成ISC的生物矿化和。
