Blast furnace slag functionalized with sulfamic acid (zwitterion) shows an extraordinary potential for the removal of biogenic amines from spiked water and real wastewater samples. The functionalized slag is characterized using scanning electron microscopy-energy dispersive spectroscopy (SEM/EDS), Fourier transform infrared spectroscopy (FTIR), and acid site density test. Its performance toward the removal of selected biogenic amines (putrescine, tyramine, and 2-phenylethylamine) is evaluated at different experimental conditions that include pH, contact time, adsorbent dosage, and initial concentration. The central composite experimental design is employed in investigating the effect of these individual factors and their interactions. The adsorption experiment results fit both the Langmuir isotherm model and pseudo-second-order kinetic model based on the computed high coefficient of determination (R2) values. Maximum adsorption capacity values of 80.64 mg g−1 for 2-phenylethylamine, 12.5 mg g−1 for putrescine, and 64.52 mg g−1 for tyramine are estimated from the Langmuir isotherm model. Hydrogen bonding interaction between the S═O groups of the functionalized slag and protonated amino groups of biogenic amines is speculated as the possible mechanism of adsorption. The prepared functionalized slag also exhibits good adsorptive removal of biogenic amines in a date palm fruit processing industrial wastewater sample.

使用两性离子功能化的高炉渣从合成和实际废水中吸附生物胺
用氨基磺酸（两性离子）功能化的高炉矿渣显示出从加标水和实际废水样品中去除生物胺的非凡潜力。使用扫描电子显微镜-能量色散光谱 (SEM/EDS)、傅里叶变换红外光谱 (FTIR) 和酸位密度测试对功能化炉渣进行表征。在包括 pH、接触时间、吸附剂剂量和初始浓度在内的不同实验条件下评估其去除选定生物胺（腐胺、酪胺和 2-苯乙胺）的性能。中心复合实验设计用于研究这些个体因素及其相互作用的影响。R 2 ) 值。根据朗缪尔等温线模型估计2-苯乙胺的80.64 mg g -1、腐胺的12.5 mg g -1和酪胺的64.52 mg g -1 的最大吸附容量值。功能化渣的 S=O 基团与生物胺的质子化氨基之间的氢键相互作用被推测为可能的吸附机制。制备的功能化渣还表现出对椰枣加工工业废水样品中生物胺的良好吸附去除。
