Implication

Experimental work demonstrates enhanced desalination performance in graphene oxide membranes, indicating new design strategies for water purification.

Key Points

This research aims to improve the performance and stability of graphene oxide membranes for desalination purposes.
Introduced chitosan into graphene oxide membranes through a one-pot pressure-assisted self-assembly method.
Controlled the ratio of chitosan to graphene oxide to optimize interlayer spacing and charge density.
Evaluated water permeability and salt rejection rates of the modified membranes with varying compositions.
Membranes with 0.02 mg/cm² GO and 0.15 mg/cm² CH exhibited superior rejection rates for salts such as MgSO₄, NaCl, and MgCl₂.
Achieved the highest water permeability due to optimal size-sieving and ion exclusion mechanisms.
Stronger structural stability was noted in the presence of hydrogen bonding and electrostatic interactions between GO and chitosan.
