Nowadays biosorption technology is primarily used as a potent tool for solving the environmental pollution, as compared to conventional methods because of its low cost, and environmental safety. It is not associated with secondary pollutions during its operation. The present study is based on checking the capacity of live and pretreated biomass of Aspergillus species for the biosorption of lead metal ions. Among the five species tested, the best results were obtained for A. niger. While the minimum and maximum removals of lead metal ion by live A. niger biomass were 3.84 and 16.42 mg/g at 2 mM and 9 mM concentration respectively, it was increased to 31.25 and 48.44 mg/g respectively at same base concentration for pretreated biomass. Overall, it was observed that pretreated alkali biomass of test fungal species is a potent biosorbent for the metal ions.

碱预处理真菌生物质对铅金属离子的去除和解毒的生物吸附潜力。

与传统方法相比，由于其低成本和环境安全性，如今生物吸附技术主要用作解决环境污染的有效工具。它在操作过程中与二次污染无关。本研究基于检查曲霉菌种的活生物和预处理生物质对铅金属离子的生物吸附能力。在测试的五个物种中，黑曲霉获得了最佳结果 。而活黑曲霉对铅金属离子的最小和最大去除量  在2 mM和9 mM浓度下，生物量分别为3.84和16.42 mg / g，在相同的碱浓度下，预处理后的生物量分别增加到31.25和48.44 mg / g。总体而言，观察到测试真菌物种的预处理碱生物质是金属离子的有效生物吸附剂。
