Synthesis and Characterization of Cassava Bark Nanoparticles

Abstract

Synthesis and characterization of cassava bark nanoparticles (CBNPs) was carried out using ball milling at 36, 48, 60 and 72 hours. The morphology study was done using SEM and the Gwyddion software was used to determine the particle sizes from the SEM images. The particle distribution for the un-milled cassava bark (CB) was between 1.25 + 0.06 to 19.92 + 1.00 µm, while after milling for 36, 48, 60 and 72 hours the average particle size were 4.07 + 0.20, 4.00 + 0.20 µm, 80.90 + 4.05, 74.50 + 3.73 nm respectively. 13.68 + 0.68 nm was obtained by XRD using Scherrer equation after milling for 72 hours and the XRD results revealed the presence of compounds such as SiO2, CaCO3 and KAlSi3O8. TEM was used to determine nanoparticle size distribution after milling for 72 hours and the particle size ranged from 9.73 + 0.49 to 114.60 + 5.73 nm for cassava bark nanoparticles (CBNPs), EDX results showed trace element of Si, Ca, K, Fe, Al, O in the CB milled for 72hours.

Green Corrosion Inhibitory Potentials of Cassava Plant (Manihot esculentaCrantz) Extract Nanoparticles (CPENPs) in Coatings for Oil and Gas Pipeline

“…From the estimated amount of cassava stem waste generated it shows that enough can be obtained for processing into useful application. Cassava stem can be fed to pigs, poultry, dairy cattle [45] and biochar production [46].…”

“…All of which helps improve the properties of metallic coatings [47,48]. This chapter discuss the synthesis and characterization of CPENPs which can be used as additives to coatings for corrosion protection, especially coatings for oil and gas applications due to the properties as discussed by Kolawole et al [46][47][48]. Therefore, CPENPs should not be left to waste as they are useful for additives in coatings.…”

Evaluation the Effect of Velocity and Temperature on the Corrosion Rate of Crude Oil Pipeline in the Presence of CO2/H2S Dissolved Gases

“…The results show that crude oil has the most significant effect of in the rate of corrosion of steel and increased as temperature and fluid velocity increased. Kolawole et al [16] give a comprehensive review of CO 2 and H 2 S corrosion problems in API 5L steel pipeline and the proper methods to control the corrosion problems. They showed that the primary causes of corrosion in oil and gas pipelines are the presence of water together with acid gases (CO 2 and H 2 S).…”
