The adsorption of metal ions from wastewater using Schiff base cellulose bearing pendulant heterocyclic chelating groups (MC-Tz) as a sorbent is the subject of this paper. Solid state 13C-NMR, FT-IR, SEM, and XRD spectroscopy, as well as TGA and XRD were utilized to examine the adsorbent. The batch sorption process used pH, adsorbent dose, initial adsorbate concentration, temperature, as well as contact time to calculate the metal ion levels. The optimum pH-6.0, with the complexation reaction and ion exchange phase as the mechanisms at work. To investigate the equilibrium concentration and temperature-dependent rate constants, various models, such as the Langmuir, Freund, Temkin, and Redlich–Peterson adsorption isotherm were utilized. Maximum adsorption capacity of the modified cellulose (MC-Tz) towards Lead(II), Copper(II), Nickel(II), and Cadmium(II) were found to be 453.2, 485.5, 473.2, and 455.6 mg/g respectively. A Kinetic study shows that the Langmuir is more in agreement with the Pseudo-second order Kinetic model. Adsorption–Desorption experiments over four cycles demonstrated the feasibility of the sorbent's regeneration potential and the measured values of enthalpy and entropy explain the essence of the adsorption process. The objective of this research is to discover non-toxic, environmentally friendly adsorbent biodegradable components and to conduct evaluations to determine their use in wastewater treatment.

使用带有悬垂杂环螯合基团 (MC-Tz) 的席夫碱纤维素作为吸附剂从废水中吸附金属离子是本文的主题。使用固态 13C-NMR、FT-IR、SEM 和 XRD 光谱以及 TGA 和 XRD 来检查吸附剂。批量吸附过程使用 pH 值、吸附剂剂量、初始吸附物浓度、温度以及接触时间来计算金属离子水平。最适pH-6.0，以络合反应和离子交换相作为起作用的机制。为了研究平衡浓度和温度相关的速率常数，使用了各种模型，例如朗缪尔、弗氏、Temkin 和 Redlich-Peterson 吸附等温线。改性纤维素 (MC-Tz) 对铅 (II)、铜 (II)、镍 (II)、和镉 (II) 分别为 453.2、485.5、473.2 和 455.6 毫克/克。动力学研究表明朗缪尔更符合伪二阶动力学模型。四个循环的吸附-解吸实验证明了吸附剂再生潜力的可行性，焓和熵的测量值解释了吸附过程的本质。这项研究的目的是发现无毒、环保的吸附剂可生物降解成分，并进行评估以确定它们在废水处理中的用途。四个循环的吸附-解吸实验证明了吸附剂再生潜力的可行性，焓和熵的测量值解释了吸附过程的本质。这项研究的目的是发现无毒、环保的吸附剂可生物降解成分，并进行评估以确定它们在废水处理中的用途。四个循环的吸附-解吸实验证明了吸附剂再生潜力的可行性，焓和熵的测量值解释了吸附过程的本质。这项研究的目的是发现无毒、环保的吸附剂可生物降解成分，并进行评估以确定它们在废水处理中的用途。
