The research was aimed at checking the possibility of using the Chrysanthemum (Chrysanthemum indicum) as a sorbent for the removal of heavy metals. The chrysanthemum was divided into flower petals, stems, and leaves to check the affinity for the metals tested. In the work, equilibrium and kinetic modeling of the process was carried out by selecting nonlinear models with the best fit. The tested material was characterized by high sorption capacity in relation to lead ions, amounting to 87–89 mg/g. The equilibrium model that best describes the lead ion sorption process on Chrysanthemum indicum is the Langmuir model, while the kinetic model is the pseudo-second-order model. The performed tests of metal recovery from the surface of the tested material allowed for its recovery in the range of 43–55% with the use of acetic acid.

该研究旨在检查使用菊花（Chrysanthemum indicum）作为吸附剂去除重金属的可能性。菊花被分为花瓣，茎和叶，以检查对测试金属的亲和力。在工作中，通过选择最佳拟合的非线性模型对过程进行平衡和动力学建模。被测材料的特点是对铅离子的吸附能力高，达87-89 mg / g。最能描述菊花中铅离子吸附过程的平衡模型是Langmuir模型，而动力学模型是伪二阶模型。从被测材料表面进行的金属回收率测试表明，使用乙酸可使金属回收率在43-55％之间。
