Abstract
Non-viable fungal biomass of Aspergillus niger, coated with iron oxide was investigated for its potential to remove arsenic from an aqueous solution. A. niger biomass coated with iron oxide showed maximum removal (approximately 95% of As(V) and 75% of As(III)) at a pH of 6. No strong relationship was observed between the surface charge of the biomass and arsenic removal.
摘要
研究了包覆有氧化铁的黑曲霉非活性真菌生物质从水溶液中去除砷的潜力。包覆有氧化铁的黑曲霉生物质在pH值为6时表现出最大去除率（约95%的五价砷和75%的三价砷）。未观察到生物质表面电荷与砷去除之间存在强相关性。
