Cadmium(II) is well known for its toxicity and its removal is a prominent task in the field of environmental research. Trifolium resupinatum (TR) has been investigated for the biosorptive removal of Cd(II). The material was characterized by FTIR and SEM. These well established the nature of functional groups and the surface morphology. The effects of various process parameters including time of contact, concentration, pH and temperature were optimized. The maximum removal was observed at 20 min and a pH of7. The equilibrium was described by the Langmuir model showing the maximum biosorption of 31.95 mg/g. The binding of Cd(II) ions was found to be endothermic in nature. The biosorbent from T. resupinatum was found to adsorb potentially the toxic metal ions from its aqueous solutions.

镉（II）的毒性众所周知，在环境研究领域，其去除是一项重要任务。研究了白三叶草（TR）对Cd（II）的生物吸附去除。该材料通过FTIR和SEM表征。这些很好地确立了官能团的性质和表面形态。优化了各种工艺参数的影响，包括接触时间，浓度，pH和温度。在20分钟和pH为7时观察到最大去除。朗格缪尔模型描述了该平衡，表明最大生物吸附为31.95 mg / g。发现Cd（II）离子的结合本质上是吸热的。发现来自苏云金芽孢杆菌的生物吸附剂潜在地从其水溶液中吸附有毒金属离子。
