摘要

在本研究中，该值小于1，表明ATS对金属离子的吸附是有利的。经ATS处理后，重金属含量分别降低了88% (Ni)、82.9% (Cd)、81.5% (Cu)、74.5% (Cr)和68.9% (Pb)。结果表明，利用资源丰富、当地可获得、成本低廉的聚四氟乙烯秸秆作为吸附剂处理纺织废水中的金属离子具有经济可行性。

Research Article Batch Sorption Experiments: Langmuir and Freundlich Isotherm Studies for the Adsorption of Textile Metal Ions onto Teff Straw (Eragrostis tef) Agricultural Waste

�� value in the present investigation was less than one, indicating that the adsorption of the metal ion onto ATS is favorable. After treatment with ATS the levels of heavy metals were observed to decrease by 88% (Ni), 82.9% (Cd), 81.5% (Cu), 74.5% (Cr), and 68.9% (Pb). Results indicate that the freely abundant, locally available, low-cost adsorbent , Teff straw can be treated as economically viable for the removal of metal ions from textile effluents.
