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 β-cyclodextrin (β-CD) and di-Ph 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 β-CD and DPC, pH, time, and initial concentration Exptl. results showed the maximum adsorption capacities of Basic red 46 and Rhodamine B were 101.43 mg/g and 52.33 mg/g, the adsorption behavior of two contaminants followed pseudo-second-order model and the Langmuir monolayer adsorption models. The differences in adsorption capacities on two model contaminants might due to the influence of dye structure. In conclusion, cyclodextrin-based nanosponges are a promising kind of environment-friendly materials in water treatment. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0HPLC of Formula: 102-09-0).
Diphenyl carbonate (cas: 102-09-0) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.HPLC of Formula: 102-09-0
