Abstract Aluminum based metal-organic framework using a di-carboxylate linker succinic acid (Al-SA MOF), are synthesized in water with minimal generation of secondary pollutants. The physicochemical properties of Al-SA MOF were examined, followed by its utility for the adsorption of Acid Black 1 (AB1) in aqueous media. Influences of key parameters such as pH, contact time, initial AB1 concentration, temperature, and selectivity on the adsorption process were assessed. A series of adsorption mechanisms are proposed, which involve electrostatic, hydrogen bonding, and hydrophobic interactions. These findings suggest that Al-SA MOF is a potent candidate in removing complex azo dyes molecules from aqueous media.

铝基金属有机骨架的绿色合成用于从水性介质中去除偶氮染料酸性黑1

摘要 使用二羧酸连接基琥珀酸 (Al-SA MOF) 的铝基金属有机骨架在水中合成，产生的二次污染物最少。研究了 Al-SA MOF 的理化性质，然后研究了其在水性介质中吸附酸性黑 1 (AB1) 的效用。评估了关键参数如 pH 值、接触时间、初始 AB1 浓度、温度和选择性对吸附过程的影响。提出了一系列吸附机制，包括静电、氢键和疏水相互作用。这些发现表明，Al-SA MOF 是从水性介质中去除复杂偶氮染料分子的有效候选物。
