Environmental degradation due to water pollution, air pollution and soil pollution has a detrimental effect and create ecological imbalance. These factors are also responsible for the large scale introduction of heavy metal ions into the environment. Conventional treatment methods for the removal of heavy metal ions are not so advantageous as these are highly expensive and also produces toxicant. Keeping this view in the mind, the present study was framed to determine the biosorption of heavy metal ions using Solanum nigrum L. leaf biomass alone and also with Aspergillus oryzae treated S. nigrum leaf biomass. Solanum nigrum L. leaf biomass was used as biosorbent for the biosorption of cobalt, copper, iron,lead and zinc.Unaided S. nigrum leaf biomass was the better absorbant of lead (Pb) whereas when inoculated with A. oryzae cobalt (Co) was more biosorbed than any other heavy metal. Overall, the results of the present study propose that the traditional plant S. nigrum could be used for the bioadsorption of heavy metals.

真菌预处理对龙葵叶片生物量的重金属生物吸附作用

由水污染，空气污染和土壤污染引起的环境退化具有有害作用，并造成生态失衡。这些因素也导致将重金属离子大规模引入环境。用于去除重金属离子的常规处理方法不是很有利，因为它们很昂贵并且还会产生毒物。牢记这一观点，本研究旨在确定仅使用茄黑茄叶生物量以及米曲霉处理过的猕猴桃叶生物量对重金属离子的生物吸附。龙葵叶片生物量被用作生物吸附剂，用于钴，铜，铁，铅和锌的生物吸附。黑曲霉叶片生物量是铅（Pb）的更好吸收剂，而与米曲霉钴（Co）相比，它比其他重金属具有更高的生物吸附性。总体而言，本研究的结果表明，传统植物黑链霉菌可用于重金属的生物吸附。
