Abstract

In this study, four types of "Juá" stem barks (Ziziphus joazeiro) were investigated for the removal of Cu(II) from aqueous solutions. The tested samples included natural coarse barks, and barks washed with water, ethanol-water, and NaOH solutions. The solvent-modified materials simulated the waste of the industrial extraction of saponins from bark. The valorization of these processing residues as sorbents was evaluated. The NaOH-washed sorbent exhibited the highest sorption capacity for Cu(II) (maximum sorption capacity 32 mg g). Ion exchange process between copper and exchangeable surface cations and electrostatic attraction of copper with carboxylate and phenolate groups were identified as the primary sorption mechanisms. Desorption tests revealed that a large portion of the metal sorbed (80%) was easily released from the sorbent thus suggesting, in line with the proposed mechanisms, the existence of weak sorbate-sorbent interactions. The sorptive process was found to be exothermic (∆H° =  - 48.1 ± 13.5 kJ.mol) and thermodynamically favorable at lower temperatures.

摘要

在这项研究中，研究了四种“Juá”茎皮（Ziziphus joazeiro），以去除水溶液中的 Cu(II)。测试的样品包括天然粗皮和用水、乙醇-水和 NaOH 溶液洗涤过的皮。经过溶剂改性的材料模拟了从树皮中提取皂素的工业废料。评估了这些加工废料作为吸附剂的利用价值。NaOH 洗涤后的吸附剂对 Cu(II)的吸附容量最高（最大吸附容量为 32mg/g）。铜与可交换表面阳离子之间的离子交换过程和铜与羧酸盐和酚盐基团之间的静电吸引被确定为主要的吸附机制。解吸测试表明，大部分被吸附的金属（80%）很容易从吸附剂中释放出来，这与所提出的机制一致，表明存在较弱的吸附剂-吸附质相互作用。吸附过程是放热的（∆H°=−48.1±13.5kJ/mol），在较低温度下热力学上是有利的。
