Herein, a metal-organic framework (ZIF-8) was synthesized and functionalized with 3-aminopropyl trimethoxy silane (APTMS). The synthesized materials (ZIF-8 and ZIF-8@APTMS) were characterized using various techniques, including SEM, TEM, FTIR, Raman, XRD, BET, and TGA. Pollutant (Direct Red 23(DR23)) removal ability of the materials from aqueous media was investigated. In addition, the antibacterial activity of the synthesized materials was investigated with Staphylococcus aureus, and Escherichia coli by three methods, including diffusion agar, minimum inhibitory concentration (MIC)/ minimum bactericidal concentration (MBC), and viable cell count. The effect of possible interactions with key parameters on pollutant removal was studied. The results showed that the DR23 adsorption obeyed the pseudo-second-order kinetic and the Freundlich isotherm with the experimental adsorption data. The maximum adsorption capacity and removal efficiency of DR23 with ZIF-8@APTMS adsorbent was 2159 mg/g and 93.59 %, respectively. The data from this study concluded that ZIF-8@APTMS was significantly capable of dye adsorbing from aqueous media. The antibacterial activity of the materials is almost similar and is slightly higher in the ZIF-8 sample. The MBC was obtained for both bacteria with the same MIC numbers, indicating the toxicity of similar materials as an inhibition zone. The growth inhibition halo was more visible on S. aureus than in E. coli. The percentage of bacterial decrease in the viable cell count method was 92 % on S. aureus and 20 % on E. coli.

本文中，合成了金属有机骨架（ZIF-8）并用3-氨丙基三甲氧基硅烷（APTMS）进行了功能化。使用多种技术对合成材料（ZIF-8和ZIF-8 @ APTMS）进行了表征，包括SEM，TEM，FTIR，拉曼，XRD，BET和TGA。研究了该材料从水性介质中的污染物（直接红23（DR23））去除能力。此外，用金黄色葡萄球菌和大肠杆菌研究了合成材料的抗菌活性。通过三种方法，包括扩散琼脂，最小抑菌浓度（MIC）/最小杀菌浓度（MBC）和活细胞计数。研究了关键参数可能相互作用对污染物去除的影响。结果表明，DR23吸附符合拟二级动力学和Freundlich等温线与实验吸附数据。ZIF-8 @ APTMS吸附剂对DR23的最大吸附量和去除效率分别为2159 mg / g和93.59％。这项研究的数据得出结论，ZIF-8 @ APTMS能够显着吸附水性介质中的染料。该材料的抗菌活性几乎相似，并且在ZIF-8样品中略高。对于两种具有相同MIC数的细菌，均获得了MBC，表明类似物质作为抑制区的毒性。金黄色葡萄球菌的生长抑制晕比在金黄色葡萄球菌中更明显大肠杆菌。活细胞计数法中细菌减少的百分比在金黄色葡萄球菌中为92％，在大肠杆菌中为20％。
