Sorption properties of fabricated film from cotton gin trash

Cotton gin trash (CGT), is an abundant waste material produced during the ginning process of cotton fibre. In this current work, biodegradable films were prepared from the whole CGT through mixing with formic acid in a single-step procedure. The preliminary results showed that the fabricated film had a higher water absorbency compared to the raw material, proportional to the amount of CGT present in the film. Furthermore, the fabricated film had notable dye removal properties comparable with the dye adsorption of granular activated carbon. The initial outcome suggests the potential application of CGT films as an adsorbent material, e.g., filter for dye separation from wastewater.
