Adsorptive Removal of Sulphonamides in Water by Graphene Oxide-Doped Porous Polycarbonate Derived From Optical Disc Waste
Tags: Universiti Malaya, Malaysia, Energy & Environment
This technology upcycles polycarbonate waste from optical discs by doping it with graphene oxide to create a porous material capable of adsorbing sulphonamides from water. The material, formed through non-solvent-induced phase separation, demonstrates high thermal stability and an enhanced surface area, making it effective for wastewater treatment. The study optimized adsorption conditions and confirmed that the material follows Langmuir isotherms with a chemisorption mechanism. It was tested with various sulphonamides, showing consistent performance across water matrices and reusability up to four cycles. The innovation addresses both e-waste management and water remediation.
