Electrospun adsorbent membrane of PLA containing chitosan for toxic metal ions removal from aqueous solution: Effect of chitosan incorporation.

The scarcity of water resources and their pollution are vital to modern civilization. Thus, adsorptive membranes are promising candidates to be applied in the filtration systems to improve the water quality. In summary, this study investigated the effect of chitosan (CS) in the morphological, chemical, and physical aspects of PLA-based membranes incorporating chitosan obtained by electrospinning process, their adsorption behavior in multielement aqueous systems containing Cr, Cu, Zn, Mn , Ni, and Cd in pH 4, and the possible removal mechanism on the composite electrospun membrane's surface.

Recycling and reuse of waste from electricity distribution networks as reinforcement agents in polymeric composites.

Of the waste generated from electricity distribution networks, wooden posts treated with chromated copper arsenate (CCA) and ceramic insulators make up the majority of the materials for which no effective recycling scheme has been developed. This study aims to recycle and reuse this waste as reinforcement elements in polymer composites and hybrid composites, promoting an ecologically and economically viable alternative for the disposal of this waste. The CCA wooden posts were cut, crushed and recycled via acid leaching using 0.
