cotton lint, nanoparticles, and nanocellulose.Abstract
The aim of the current study is to prepare nanocellulose (NC) from agricultural wastes: cotton
lint rather than throwing it into waste which increases pollution of the environment and thereby
reduces environmental pollution to some extent. In this study, the nanocellulose was prepared
by acid hydrolysis using sulfuric acid at a concentration (30) % for cotton lint to dissolve the
raw materials by sulfuric acid and extract cellulose. It also converts it to nanocellulose by using
renewable and advanced methods by the ultrasonic processor for different times at (30-180)
minutes. And the outcome was a fine powder with good quality that could have been used in
other processes and methods. By completely removing lignin and hemicellulose, Atomic force
microscope (AFM) photos demonstrated the smooth surface and small nanoparticles of cotton
lint-derived Nano cellulose, while Fourier transform infrared spectroscopy (FTIR)
measurements demonstrated the purity of cellulose. 3.303 nm is reported to be the average
roughness of cotton lint-derived nanocellulose. There are numerous uses for the manufactured
cellulose nanoparticles. Because of this, we think that in the near future, cotton lint with a high
cellulose content will be a great source of inexpensive raw materials.
