Cyclodextrin-based nanosponges (CDNS) are a novel kind of polymers belonged to cross-linked derivatives of cyclodextrins, and they are safe, biodegradable materials with appreciable toxicity to the environment. In this work, CDNS were fabricated in one-step solvothermal method by beta-cyclodextrin (beta-CD) and diphenyl carbonate (DPC), for the removal of dyestuffs from wastewater using two of the familiar dyes as the model contaminant. It was systematically investigated by the influence of the amount of adsorbent, the molar ratio of beta-CD and DPC, pH, time, and initial concentration. Experi...
