The expulsion of iron from water is an essential issue. Exceeding iron concentrations in water, it become more toxic and cause several troubles for human health and environment. The biosorption is the upcoming mechanism to treat the iron from wastewater. Microorganisms perform an important function in the bioremediation of wastewater. This study was conducted to investigate the removal of iron by dried biomass of Aspergillus niger (A.niger). The dried A. niger was tested as a sorbent for the removal of iron from wastewater. The effects of various experimental parameters as initial iron concentration, amount of biomass, contact time and the initial pH solution were examined and optimal experimental conditions were obtained. The obtained adsorption results were fitted to the Langmuir, Freundlich, and Temkin equations. The study showed that dried A. Niger biomass in high concentration 4 g/100 ml was found to be more effective in the removal of iron from water at pH 3 with contact time 60 min. the A. Niger successfully removed iron and has ability to be regenerated and reused in the removal process.

从水中排出铁是一个基本问题。超过水中的铁浓度，它会变得更具毒性，并对人类健康和环境造成一些麻烦。生物吸附是即将出现的处理废水中铁的机制。微生物在废水的生物修复中发挥着重要作用。本研究旨在研究黑曲霉( A.niger ) 干燥生物质对铁的去除作用。干燥的A. niger被测试作为吸附剂从废水中去除铁。考察了初始铁浓度、生物质量、接触时间和初始pH溶液等各种实验参数的影响，得到了最佳实验条件。获得的吸附结果符合 Langmuir、Freundlich 和 Temkin 方程。研究表明，在 60 分钟的接触时间下，发现高浓度 4 g/100 ml 干燥的A. Niger生物质在从水中去除 pH 3 的铁方面更有效。A. Niger成功地去除了铁，并且在去除过程中具有再生和再利用的能力。
