In this study, silver nanoparticles were prepared and used for separation and preconcentration of manganese from biological samples. The technical feasibility of silver nanoparticles for manganese removal was investigated under batch studies. The effects of different parameters such as pH of solution, time (t), amounts of PAN (E), and silver nanoparticles (N) on the adsorption of manganese by silver nanoparticle were investigated using factorial design and response surface methodology based on Box-Behnken design. Thermodynamic parameters indicate the adsorption process to be exothermic. The limit of detection of the proposed method followed by inductively coupled plasma was found to be 0.08 µg L(-1). The method was applied to determine of manganese in biological samples.
在这项研究中，制备了银纳米粒子，并将其用于从生物样品中分离和预浓缩锰。在批量研究下，研究了银纳米粒子对锰去除的技术可行性。使用析因设计和基于 Box-Behnken 设计的响应面法研究了不同参数（如溶液 pH 值、时间 (t)、PAN (E) 用量和银纳米粒子 (N)）对银纳米粒子吸附锰的影响。热力学参数表明吸附过程是放热的。发现所提出的方法（随后用电感耦合等离子体法）的检测限为 0.08μg L(-1)。该方法用于测定生物样品中的锰。
