A C₈-and-amino-bifunctionalized ordered mesoporous organosilica (C₈-AMS) was prepared in a deep eutectic solvent—a green solvent—that was used as the reaction medium for this procedure instead of organic solvents or other catalyst for the first time. This method provided a nontoxic way for C₈ grafting and obtaining an ordered mesoporous organosilica material with both hydrophilic and hydrophobic groups. Besides advantages such as its large surface area, regular and uniform pore size, and hydrothermal stability, the obtained bifunctionalized C₈-AMS also have two main functional groups in the obtained structure, C₈ and amino, which enriched the adsorption mechanism of the material and as a result improved the adsorption selectivity of C₈-AMS. Its performance as an adsorbent was estimated in extracting trace triazine herbicides from watermelon using solid-phase extraction (SPE) followed by high-performance liquid chromatography (HPLC). The proposed method provided satisfactory features in terms of linearity (0.01–2.00 μg g⁻¹), limits of detection (2.9–5.1 ng g⁻¹), accuracy (recovery: 85.7–101.7%), and precision (intra-day and inter-day RSDs: 1.68–2.60% and 3.05–4.01%).

在深共熔溶剂（一种绿色溶剂）中制备了AC ₈和氨基双官能化的有序介孔有机二氧化硅（C ₈ -AMS），该溶剂首次用作有机溶剂或其他催化剂的反应介质。该方法为C ₈接枝和获得具有亲水和疏水基团的有序介孔有机二氧化硅材料提供了一种无毒的方法。除了具有较大的表面积，规则且均匀的孔径以及水热稳定性等优点外，所得双官能化C ₈ -AMS在结构中还具有两个主要官能团C ₈和氨基，丰富了材料的吸附机理，从而提高了C ₈ -AMS的吸附选择性。在使用固相萃取（SPE）继之以高效液相色谱（HPLC）从西瓜中萃取痕量三嗪除草剂时，估计了其作为吸附剂的性能。所提出的方法在线性度（0.01–2.00μgg ^-1），检测限（2.9–5.1 ng g ^-1），准确性（回收率：85.7–101.7％）和精度（日内和定量）方面均提供令人满意的功能。日内RSD：1.68–2.60％和3.05–4.01％）。
