Acetylated materials have been applied successfully in oily water remediation with some degree of success. Many of these materials which have been acetylated are, however, from seasonal fruits and other plant parts. This work reports the successful acetylation of silica extracted from diatomaceous earth by refluxing silica and acetic anhydride using 1% N-bromosuccinimide as a catalyst. The functionalization was confirmed by the presence of absorption bands at 1406 cm⁻¹ (C–O) and 1568 cm⁻¹ (C=O) on an IR spectrum and the presence of C, Si, and increased amount of O on the EDX spectrum. The synthesized materials were applied in the optimization of the removal of oil from synthetic oily wastewater using response surface methodology giving a percentage oil removal of 99.7%. The optimum conditions for oil removal were as follows; 7867 mg/L oil concentration, with adsorbent dosage of 0.001 g and a duration of 21.6 h, and the adsorption capacity under these conditions was found to be 1039 mg/g. The outcomes proved that acetylated silica is an excellent material for oil adsorption and can therefore be used in oil spill clean-ups.

乙酰化材料已成功应用于油性水修复中，并取得了一定程度的成功。但是，许多已被乙酰化的材料来自时令水果和其他植物部位。这项工作报道了使用1％N-溴代琥珀酰亚胺作为催化剂，通过回流二氧化硅和乙酸酐，成功地将从硅藻土中提取的二氧化硅乙酰化。通过在1406 cm ^-1（C–O）和1568 cm ^-1处存在吸收带来证实功能化IR光谱上的（C = O）以及EDX光谱上存在的C，Si和增加的O量。使用响应表面方法将合成材料应用于优化从合成含油废水中除油的应用，从而得出除油百分比为99.7％。除油的最佳条件如下：油浓度为7867 mg / L，吸附剂量为0.001 g，持续时间为21.6 h，在这些条件下的吸附容量为1039 mg / g。结果证明，乙酰化二氧化硅是一种出色的吸油材料，因此可用于溢油清理。
