The current study aimed to assess the effectiveness of biochar formed from algae in the removal of Cr(VI) through the process of impregnating brown algae Sargassum hemiphyllum with KHCO. The synthesis of KHCO-activated biochar (KBAB-3), demonstrating remarkable adsorption capabilities for Cr(VI), was accomplished utilizing a mixture of brown algae and KHCO in a mass ratio of 1:3, followed by calcination at a temperature of 700 °C. Based on the empirical evidence, it can be observed that KBAB-3 shown a significant ability to adsorb Cr(VI) within a range of 60-160 mg g across different environmental conditions. In addition, the KBAB-3 material demonstrated the advantageous characteristic of easy separation, allowing for the continued maintenance of a high efficiency in removing Cr(VI) even after undergoing numerous cycles of reuse. In conclusion, the application of KBAB-3, a novel adsorbent, exhibits considerable prospects for effective removal of Cr(VI) from diverse water sources in the near future.
当前的研究旨在通过用KHCO浸渍半叶马尾藻来评估藻类形成的生物炭在去除六价铬方面的有效性。利用质量比为1:3的褐藻和KHCO混合物合成了对六价铬具有显著吸附能力的KHCO活化生物炭（KBAB - 3），随后在700℃下煅烧。基于实验证据，可以观察到KBAB - 3在不同环境条件下对60 - 160mg/g范围内的六价铬具有显著的吸附能力。此外，KBAB - 3材料具有易于分离的优势特性，即使经过多次重复使用循环后，仍能持续保持高效去除六价铬的能力。总之，新型吸附剂KBAB - 3的应用在不久的将来对于从各种水源中有效去除六价铬展现出可观的前景。
