Role of plasma process gas on permeate flux augmentation of cellulose nitrate membrane for mud water treatment.

A comparative study between Nitrogen (N) and Argon (Ar) plasma is carried out to investigate its effect on surface morphology, hydrophilicity, permeate flux and ageing of cellulose nitrate polymeric membranes in the present work. Langmuir probe and Optical Emission Spectroscopy are used to characterize the plasma. The SEM analysis reveals the noticeable macro-void creations and pore enlargement for both N and Ar plasma.
