Abstract
The accumulation of Cu2+ in water is a potential threat to human health and environment. Dicarboxylic nanocellulose (DNC) with rich carboxyl groups was prepared through the NaIO4–NaClO2 sequential oxidation method to efficiently remove copper ions, and the Cu2+ adsorption properties and cost were studied. The maximum adsorption capacity reached 184.2 mg/g at pH 6 and an adsorbent dose of 5 g/L. Theoretically, the maximum adsorption capacities of monocarboxylic nanocellulose (MNC), DNC, and tricarboxylic nanocellulose (TNC) with carboxyl groups as the main adsorption sites were calculated to be 228.7, 261.3, and 148.1 mg/g, respectively. The Cu2+ adsorption costs of MNC, DNC, and TNC were calculated and compared with those of powdered activated carbon (PAC). The Cu2+ adsorption capacity of DNC is higher than that of PAC, and the adsorption cost is close to or lower than that of PAC, demonstrating that the DNC prepared by sequential oxidation of NaIO4–NaClO2 has competitive adsorption capacity and cost in the treatment of wastewater containing Cu2+.
