Chitosan, malachite green dye, hydrophilic, contact angle.Abstract
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
