Two optimized methods, based on epoxy-amino reactivity of the Cellulose fibres (Cell) modified with diethylenetriamine (Cell‒DETA), (3-Glycidyloxypropyl)trimethoxysilane (Cell-Glymo), Lignin modified with epichlorohydrine (EL) and Tannic acid (TA), as an additional crosslinker, were developed for the production of the bio-renewable Cell-EL and Cell-EL-TA membranes. The influences of pH, contact time, adsorbent dose, and temperature on adsorption performances were studied by batch adsorption tests. The calculated capacities: 53.9, 99.9, 97.8 and 63.5, 115.8, 127.5 mg g⁻¹ for Ni²⁺, Pb²⁺, Cr(VI) using Cell-EL and Cell-EL-TA, respectively, were obtained from Langmuir model fitting at 25 °C. The thermodynamic parameters indicated spontaneous and low endothermic processes. The results of the kinetic study, i.e. pseudo-second-order (PSO) and Weber-Morris (W-M), suggest an intra-particle diffusion as a rate-limiting step. The semi-empirical quantum chemical calculations aided the analysis of the non-specific and specific adsorbent/adsorbate interactions and their contribution to the overall bonding mechanism. Membrane utility was confirmed by performing a bed column study. In general, three main environmental issues of the present study, biodegradability of the used membrane, desorption efficiency, and development of the technology for the effective effluent water treatment and safe disposal of by-products highly conform to the demand of integrated environmental management system applicability in practice.

两种优化的方法，基于用二亚乙基三胺（Cell‒DETA）改性的纤维素纤维（Cell），（3-缩水甘油氧基丙基）三甲氧基硅烷（Cell-Glymo），经表氯醇（EL）和单宁酸（TA）改性的木质素的环氧氨基反应）作为一种额外的交联剂，被开发用于生产可生物更新的Cell-EL和Cell-EL-TA膜。通过分批吸附试验研究了pH，接触时间，吸附剂量和温度对吸附性能的影响。计算出的容量：Ni 2 ⁺，Pb ^2+的53.9、99.9、97.8和63.5、115.8、127.5 mg g ^-1分别在25°C下从Langmuir模型拟合获得使用Cell-EL和Cell-EL-TA的Cr（VI）。热力学参数表明自发和低吸热过程。动力学研究的结果，即伪二阶（PSO）和Weber-Morris（WM）建议将粒子内扩散作为限速步骤。半经验量子化学计算有助于分析非特异性和特异性吸附剂/被吸附物之间的相互作用及其对整体键合机理的贡献。通过进行床柱研究确认了膜的效用。通常，本研究的三个主要环境问题，用过的膜的生物降解性，解吸效率以及有效废水处理和副产物安全处理技术的发展高度符合综合环境管理系统适用性的要求。在实践中。
