Polycyclic aromatic hydrocarbon adsorption using ß-cyclodextrin functionalized rice husk biochar: Fixed-bed column studies

Recently, numerous adsorption systems have been examined comprehensively on a laboratory scale to explore the practical feasibility of a particular adsorbent-adsorbate system. However, ß-cyclodextrin functionalized rice husk biochar (CD-RHB) as an adsorbent for carbazole removal under fixed-bed adso...
