Preparation of Poly (Allylthiourea-Co-Acrylic Acid) Derived Carbon Materials and Their Applications in Wastewater Treatment.

ABSTRACT: Functional carbon materials have been developed and applied in various sewage treatment applications in recent years. This article reports the fabrication, characterization, and application of a new kind of poly (allylthiourea-co-acrylic acid) (PAT⁻PAC) hydrogel-based carbon monolith. The results indicated that the poly acrylic acid component can endow the PAT⁻PAC hydrogel with an increased swelling ratio and enhanced thermal stability. During the carbonization process, O⁻H, N⁻H, C=N, and ⁻COO⁻ groups, etc. were found to be partly decomposed, leading to the conjugated C=C double bonds produced and the clear red shift of C=O bonds. Particularly, it was found that this shift was accelerated under higher carbonization temperature, which ultimately resulted in the complex conjugated C=C networ
