  Abstract

In this study, three different saccharides (glucose, 棺-cyclodextrin, and kraft pulp) were hydrothermally carbonized for the synthesis of hydrochar with excellent adsorption capacity, and their adsorption behaviors were studied. Glucose and 棺- cyclodextrin were successfully converted into hydrochars, whereas kraft pulp was not. This study on the morphology and the chemical structure of the hydrochars revealed that the structures of the hydrochars were significantly influenced by the precursor type. The macropore and negatively charged surface of the glucose-based hydrochar were highly beneficial for the organic pollutant adsorption. Methylene blue was adsorbed monolayerly on the hydrochar surfaces via chemisorption. The macropore contributed the intra-particular diffusion of methylene blue, which improved the adsorption capacity of the hydrochar. The glucose-based hydrochar showed remarkable adsorption capacity and could be reused four times.
