Carbon@ceramic 3D printed devices for bisphenol A and other organic contaminants extraction

A high efficient and versatile extraction device was prepared by coating a durable 3D printed ceramic support with a polymer-derived porous carbon. The ceramic support was coated with polyvinylidene fluoride (PVDF), which acted as binder and carbon source simultaneously, allowing to obtain a high robust and functional carbon coated device in a direct and very simple way. The so prepared device was evaluated for the extraction of the endocrine disrupting phenol, bisphenol A. It showed fast adsorption kinetics, high extraction capacity (122.5 mg g(-1)), and excellent reusability, keeping removal percentages above 90% after 10 consecutive extraction cycles. Carbon@ceramic 3D printed devices also showed good performance for the individual and simultaneous extraction of other phenolic compounds (4-tert-octylphenol and 4-tert-butylphenol), pharmaceutical products (ibuprofen, diclofenac and acetaminophen), and organic dyes (malachite green and methylene blue) in real water samples, demonstrating its potential for the removal of organic pollutants from water.
