Herein, a modified polyaniline nanocomposite containing CoFeC6N6 was prepared and tested for its sorption of Pb2+ and Ni2+ ions from aqueous solutions. The adsorbent was characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, Brunauer–Emmett–Teller and Fourier transform infrared analyses. The adsorption percentage increased with increasing CoFeC6N6 in the nanocomposite material. A pseudo-second-order model and Langmuir adsorption described the behavior of the material. Additionally, the adsorption capacity was increased by increasing the temperature. The prediction of concentrations was performed using a model based on pore diffusion and the implicit finite difference method. From a mass transfer standpoint, the best data set of De for Pb2+ (1.12 × 10–9 m2 s–1) and Ni2+ (0.98 × 10–13 m2 s–1) was determined.

使用聚苯胺/ CoFeC 6 N 6纳米复合材料从水溶液中吸附Ni（II）和Pb（II）的建模和实验评估
在此，制备了包含CoFeC 6 N 6的改性聚苯胺纳米复合材料，并测试了其从水溶液中吸附Pb 2+和Ni 2+离子的能力。通过扫描电子显微镜，透射电子显微镜，X射线衍射，Brunauer-Emmett-Teller和傅立叶变换红外分析对吸附剂进行表征。吸附百分比随CoFeC 6 N 6的增加而增加在纳米复合材料中。伪二级模型和Langmuir吸附描述了材料的行为。另外，通过增加温度来增加吸附容量。使用基于孔扩散的模型和隐式有限差分法进行浓度预测。从传质的角度，确定了Pb 2+（1.12×10 –9 m 2 s –1）和Ni 2+（0.98×10 –13 m 2 s –1）的最佳数据集D e。
