UTILIZATION OF PINEAPPLE LEAVES FOR PRODUCTION OF NANO CELLULOSE AND ITS APPLICATION ALONG WITH MAGNETIC CHITOSAN FOR EFFICIENT DYE ADSORPTION AND ANTIBACTERIAL ACTIVITY | PLANT CELL BIOTECHNOLOGY AND MOLECULAR BIOLOGY

 The capabilities of a new cellulose – magnetic chitosan composite in terms of dye-adsorption and anti-bacterial action were explained in this report. Absorption spectroscopy, X-ray diffraction, absorption spectrum using Fourier transform infrared spectroscopy, and scanning electron microscopy were used to discern the prepared composites. Methylene blue (MB) was used as a model contamination in dye adsorption experiments. The sorption of the composite was investigated both actively and thermodynamically in order to aid in the removal of Methylene Blue (MB) from aqueous solution. The function of CT (Contact time) is analysed with initial values of temperature and concentration during the filtering of MB out of the aqueous-solution on the composite to check the impact of certain features. The Langmuir-adsorption model was also used to evaluate the thermodynamic parameters ▵H^o, ▵G^o, and ▵S^o. Negative-Gibbs free energy (▵G^o) signals the phenomenon of "adsorption with spontaneity," and the property of positive - adsorption enthalpy (▵H^o) indicates that the procedure is endothermic for the MB. The composite's antibacterial properties were tested against Gram-positive and Gram-negative bacteria, with minimal inhibitory concentrations (MICs) of 0.1 g/mL. This research shows that prepared composite has the ability to act as a green adsorbent as well as an anti-microbial agent, and it offers a one-of-a-kind advantageous role.
