Three corroded mediums that found in the crude oil have been applied to carbon steel specimens. The effect of the corrosion mediums concentration, application periods and times investigated. The Gravimetric method showed that sodium thio sulfate has the highest corrosion effect at all corrosion test parameters followed by sodium sulfate and sodium carbonate respectively. Each of Nano zinc oxide, Nano cotton cellulose and Nano banana cellulose protective films inhibit sodium thio sulfate corrosion effect. Anti-corrosion behaviour of the formed Nano films studied using gravimetric method (weight loss method), electrochemical method (potentiodynamic polarization) and scanning electron microscope (SEM) techniques. The Nano zinc oxide heated at 700°C shown to have better inhibition efficiency followed by Nano zinc oxide heated at 600 OC, Nano cotton cellulose and Nano banana cellulose respectively. The potentiodynamic polarization measurements showed Nano zinc oxide heated at 700°C, Nano cotton cellulose, and Nano banana cellulose the acted as mixed-type inhibitors with predominantly cathodic effectiveness. SEM techniques supported the achievement of corrosion inhibition with the presence of inhibitors.

Basic Strength

The use of metal oxides in heterogeneous base catalysis has gained a large interest due to their application in many chemical and industrial processes and is environmental friendly. Basic metal oxides are commonly used and their structures, morphology and performance can be modified by method of preparation and thermal activation. In this study, surface modified amphoteric zinc oxide was prepared via hydration-dehydration method and characterised by TGA and FTIR. The basic strength at various temperatures is characterised by FTIR and back titration analyses. The results shows that surface modified zinc oxide has the highest basic strength of 1.453mmolg-1at 400°C making it a relatively good and suitable compound for use in heterogeneous basic catalysis. This result is also supported by FTIR spectra which show possible relationship between the Lewis O2-and increasing basic strength.

The copolymer of sodium polyacrylic acid and 2-acrylamide-2-methyl propane sulfonic acid (AMPS) was prepared by radical polymerization process, the effect of mass ratio of AA/AMPS on the viscosity of AA-AMPS copolymer were investigated. Results showed that when the mole ratio of AA/AMPS was 3:1, it had the least viscosity. The dispersion stability of synthesized AA-AMPS copolymer for nanozinc oxide was tested.
