Water pollution is one of the biggest problems in the world and treatment is very important. ZIF-8 is a promising nanomaterial for water treatment. In this study, zinc imidazolate framework-8 (ZIF-8) nanoparticles were prepared via a solvothermal method. The synthesized were characterized by using several techniques and applied in emulsified oil/water separation and reuse. A combination of techniques (XRD, BET, SEM) showed that the crystalline phase of the ZIF-8 was successfully obtained by the solvothermal method. ZIF-8 exhibits a high surface area of 1146 m²/g and an average nanoparticle size 47 ± 4.6 nm. ZIF-8 exhibits a very high adsorption capacity reached 2811.1 mg/g and it was regenerated by the ethanol-washing method. The process of regeneration of ZIF-8 has proved to be efficient. ZIF-8 was regenerated by a simple ethanol-washing method; the regenerated ZIF-8 exhibited more than 98% of regeneration efficiency over three cycles.

水污染是世界上最大的问题之一，处理非常重要。ZIF-8是一种有前途的水处理纳米材料。在这项研究中，通过溶剂热法制备了咪唑锌锌骨架8（ZIF-8）纳米粒子。利用几种技术对合成物进行了表征，并应用于乳化油/水的分离和再利用。结合多种技术（XRD，BET，SEM）表明，通过溶剂热法成功获得了ZIF-8的晶相。ZIF-8的高表面积为1146 m ²/ g，平均纳米颗粒尺寸为47±4.6 nm。ZIF-8表现出非常高的吸附容量，达到2811.1 mg / g，并通过乙醇洗涤方法再生。ZIF-8的再生过程已证明是有效的。ZIF-8通过简单的乙醇洗涤方法再生；再生的ZIF-8在三个循环中显示出超过98％的再生效率。
