N-[2-(methylamino)ethyl] ethane-1,2-diaminated acrylic fibre (DAAF) derived adsorbent was prepared by the reaction of acrylic fibre with bis(2-aminoethyl)amine. Fourier transform infrared spectroscopy and scanning electron microscopy were employed for elucidating the surface functional groups and morphology of DAAF, respectively. The influence of several process variables on Hg(II) adsorption was also evaluated. Equilibrium and kinetic studies were conducted using a range of two-parameter models via nonlinear regression methods. Langmuir and pseudo-second-order models emerged the best fit for isotherm and kinetic modelling, respectively. The intraparticle diffusion studies indicate that occurrence of an adsorption process, with multi-mechanistic effect. Similarly, the maximum adsorption capacity (q_max) of 627.5 mg g⁻¹ was recorded in the study at pH 5.0, 30 °C and 15–30 min. The short equilibration time recorded in the study speaks volume of the potential application of DAAF in large-scale Hg(II) adsorption systems.

通过丙烯酸纤维与双（2-氨基乙基）胺的反应制备N- [2-（甲基氨基）乙基]乙烷-1，2-亚胺基丙烯酸纤维（DAAF）衍生的吸附剂。利用傅里叶变换红外光谱和扫描电子显微镜分别阐明了DAAF的表面官能团和形态。还评估了几个工艺变量对Hg（II）吸附的影响。通过非线性回归方法，使用一系列两参数模型进行了平衡和动力学研究。Langmuir模型和伪二阶模型分别成为等温线和动力学模型的最佳拟合。颗粒内扩散研究表明，吸附过程的发生具有多机理作用。同样，最大吸附容量（q _max在pH 5.0、30 °C和15–30 min的研究中记录到627.5 mg g ^-1）。研究中记录的短暂平衡时间说明了DAAF在大规模Hg（II）吸附系统中的潜在应用。
