This work concerns the adsorption of aromatic organic matter from river water using various doses of a simulated biochar. The water yielded five UV peaks associated with organic matters in size exclusion chromatography (SEC), corresponding to molecular weights (MW) of 10,000, 6500, 4800, 3000, and 1500 Da. Biochar removes all of these peaks with an overall adsorption of 6.4 mg-DOC/g-C, and preferentially removes organic matter with high MW. Physisorption control in a pseudo-second-order type model fits the adsorption kinetics. Biochar can therefore be used as an efficient adsorbent of organic matter in water.

利用生物炭吸附去除水中天然有机物


这项工作涉及使用不同剂量的模拟生物炭从河水中吸附芳香族有机物。水在尺寸排阻色谱 (SEC) 中产生与有机物相关的五个 UV 峰，对应于 10,000、6500、4800、3000 和 1500 Da 的分子量 (MW)。生物炭以 6.4 mg-DOC/gC 的总吸附量去除所有这些峰，并优先去除具有高 MW 的有机物。准二阶模型中的物理吸附控制符合吸附动力学。因此，生物炭可以用作水中有机物的有效吸附剂。
