A post-treatment approach using common mushroom (Agaricus bisporus)-derived chitosan was done to treat and purify a synthetic pretreated acid mine drainage (AMD) solution. Commercially available chitosan and laboratory-prepared chitosan were used as coagulants for post-treatment of AMD. Both chitosans were characterized by Fourier transform infrared (FTIR) and scanning electron microscopy energy-dispersive X-ray spectroscopy (SEM-EDX). The treatment underwent a batch testing with parameters of mixing speed, mixing time, and chitosan loading. The removal of heavy metals focused on copper, iron, and nickel. The optimum parameters of the commercially available chitosan were then employed for the performance of the laboratory-prepared chitosan to evaluate its capability as a post-treatment agent for AMD.

用实验室提取的普通蘑菇壳聚糖对酸性矿山排水进行后处理

使用普通蘑菇（双孢蘑菇）衍生的壳聚糖进行后处理，以处理和纯化合成预处理的酸性矿山排水 (AMD) 溶液。市售的壳聚糖和实验室制备的壳聚糖用作 AMD 后处理的凝固剂。两种壳聚糖均通过傅里叶变换红外 (FTIR) 和扫描电子显微镜能量色散 X 射线光谱 (SEM-EDX) 进行表征。该处理通过混合速度、混合时间和壳聚糖负载参数进行批量测试。去除重金属的重点是铜、铁和镍。然后将市售壳聚糖的最佳参数用于实验室制备的壳聚糖的性能，以评估其作为 AMD 后处理剂的能力。
