USING SUSTAINABLE GREEN ORGANIC NANOMATERIALS AS NANOCELLULOSE TO REMOVAL OF HEAVY METAL LEAD (PB) FROM AQUEOUS SOLUTIONS

The issue of removing heavy metals from various water sources is currently a serious challenge due to their hazardous bioaccumulation, as it necessitates a sustainable green treatment technology to remove them. A Fourier-Transform Infrared Spectroscopy was used to identify the nanocellulose, which detected many functional groups such as (-OH) wide (3100-3600 cm-1), (C-H) (2800-3000 cm-1), and primary distinctive peaks were found in fingerprint region of band (856 cm-1), which is attributed to stretching (C-O-C) group at β-(1→4)-glycosidic connections. When using lab starch-based nanocellulose, weighing (0.5 g), the highest removal of (91%) was obtained within (6 hours) of stirring with lowest concentration (5 ppm), while the removal of (62%) decreased, when highest concentration of (Pb) used in (60 ppm) during the same time. Whereas, the removal was increased when the amount of nanocellulose was doubled to be (1.0 g), where the removal was complete (100%) at (5 ppm), and removal was (74 %) at (60 ppm) with same reaction time. From the results, the (Pb) removal depends on many factors like duration of reaction time, amount of nanocellulose, degree of saturation, and free space available of highly catalytic oxidative sites on surface area. This paper aims to use prepared nanocellulose from lab starch to use in removal of lead (Pb) from aqueous solutions cleanly and efficiently.
