Chitosan/NC Based Bio Composite Membrane: An Impact of Varying Amount of Chitosan on Filtration Ability for the Malachite Green Dye
This study is generally focused on knowing about which appropriate quantity of chitosan with cellulose nanocrystal gives best output in terms of strength and potential to bear vaccum pressure during filtration study. It was observed that membrane MIII showed best results in filtering out the malachite green dye present in the aqueous solution of 50 PPM taken during study. The filtration study was observed under three different pH values i.e. 2.0, 5.0 and 9.0 and recorded results depicted that the first five cycles significantly remove the dye concentration ranging from 32-13 PPM, 27-7 PPM and 33-14 PPM respectively. The contact angle results for all the membrane showed hydrophilic behaviour. The thickness and the swelling behaviour also analysed and it was observed that membrane MV showed highest thickness (0.56 mm) as well as highest swelling behaviour (1.5) due to presence of high chitosan content in its composition.
