Biochars derived from three species of algae was synthesized by impregnating the green algae Ulva Ohnoi, red algae Agardhiella subulata, and brown algae Sargassum hemiphyllum with ZnCl chemical activator and employed as a long-term adsorbent for ciprofloxacin (CIP) removal from water. The results revealed that combination of brown algae and ZnCl chemical activator (ZBAB) successfully produced mesoporous biochar with excellent physicochemical characteristics and gave the best CIP adsorption capacity. The ZBAB yielded a high CIP adsorption capacity (190-300 mg g) under various parameter effects (initial pH, temperature and major ions). Throughought the surface characterization techniques, the proposed adsorption mechanisms were electrostatic interaction, π-π EDA interaction, pore filling and hydrogen bonding. Moreover, not only algal biochars exhibited innovative and potential adsorbent for rapid and effective remediate pollution from water, but combination of algal biomass and ZnCl activator also created renewable source of energy from biomass pyrolysis.
通过浸渍绿藻孔石莼、红藻亚达希亚和褐藻半叶马尾藻三种藻类，制备了三种藻类来源的生物炭，并用 ZnCl 化学活化剂将其作为一种从水中去除环丙沙星 (CIP) 的长效吸附剂。结果表明，褐藻与 ZnCl 化学活化剂（ZBAB）的组合成功地制备了具有优异物理化学特性的中孔生物炭，并具有最佳的 CIP 吸附能力。在各种参数影响（初始 pH 值、温度和主要离子）下，ZBAB 产生了高的 CIP 吸附容量（190-300mg/g）。通过表面特征技术，提出了吸附机制为静电相互作用、π-π EDA 相互作用、孔填充和氢键。此外，藻类生物炭不仅表现出了创新性和潜在的吸附剂，可用于快速有效地修复水中的污染，而且藻类生物质与 ZnCl 活化剂的结合也为生物质热解创造了可再生的能源来源。
