Efficient removal of Congo red dye from aqueous solution by adsorbent films of polyvinyl alcohol/melamine-formaldehyde composite and bactericidal effects

Removal of harmful dyes and inhabitation of bacterial growth is one of the outstanding priorities in both environmental and industrial applications. The recognition of the alarming industrial discharge and insufficiency of fresh water has prompted us to develop eco-friendly and sustainable dye adsorbent films. The present investigation reports the synthesis of melamine-formaldehyde (MF) and cross-linking of polyvinyl alcohol (PVA) with MF to...
