Nanostructured Cellulose-Based Sorbent Materials for Water Decontamination from Organic Dyes

Nanostructured materials have been recently proposed in the field of environmental remediation. The use of nanomaterials as building blocks for the design of nano-porous micro-dimensional systems is particularly promising since it can overcome the (eco-)toxicological risks associated with the use of...
