Abstract The inhibitive effect of hydroxyethyl cellulose (HEC) on mild steel corrosion in aerated 0.5 M H2SO4 solution was studied using gravimetric and electrochemical techniques. temperature inhibition also investigated. results show that functioned as a good inhibitor the environment efficiency increased with concentration inhibitor. Potentiodynamic polarization measurements revealed HEC inhibited both cathodic anodic partial reactions processes. Impedance clearly reaction by adsorption...

Hydroxyethyl cellulose (HEC) was studied as corrosion inhibitor for mild steel and aluminium in 0.5 M H 2 SO 4 solution using weight loss electrochemical techniques.The results revealed that HEC inhibited of sulphuric acid environment.Inhibition efficiency found to depend on concentration the inhibitor.Impedance adsorbed corroding metal surface while polarization show both anodic cathodic reactions but showed dissolution reaction due destabilization passive oxide film Al only...

The high cost of mineral-based fillers and their processing difficulties have necessitated the search for alternative cheaper filler materials, usually agro-waste materials such as coconut shells. shells were carbonized, pulverized, sieved into four particles sizes, namely; 63 μm, 150 300 425 μm. carbonized shell each particle size used in preparation polypropylene-filled composites at loadings 0, 10, 20, 30, 40 wt. %. control was neat polypropylene 0% addition. polypropylene/carbonized...

Purpose – The paper aims to investigate the effectiveness of hydroxypropyl methylcellulose (HPMC) as corrosion inhibitor for aluminium in 0.5 M H 2 SO 4 solution. Design/methodology/approach This study was carried out using weight loss and electrochemical techniques. Inhibition efficiency determined by comparing rates absence presence system. Quantum chemical computations were performed density functional theory assess parameters responsible inhibition process also analyse local reactivity...

Polypropylene (PP)/plasticized cassava starch (PCS) blended with and without compatibilizer (polypropylene-graft-maleic anhydride (PP-g-MA)) via melt blending were prepared for soil burial which lasted 90 days. Plasticized loadings of 0, 10, 20, 30, 40, 50 wt.% used, while pp-g-ma was used at 10 based on weight. The PP/PCS PP/PCS/PP-G-MA blends evaluated their tensile properties. It observed that the strength, elongation break, young’s modulus decreased increases in time as well content...

This paper presents the study of moisture content, hardness, bulk density, apparent porosity, tensile and flexural characteristics composite properties Luffa aegyptiaca fiber. reinforced epoxy composites have been developed by hand lay-up method with fiber untreated treated conditions for 12 Hrs 24 in different filler loading as 2:1 ratio (5%, 10%, 15%, 20% 25%). The effects on were studied. In general, fibre showed better improvement via addition modified reinforcement. However, improved...

Adsorption behaviour and corrosion rate of Sodium carboxymethyl cellulose on aluminium was studied. Different concentration levels (Na-CMC) solution were applied several prepared polished coupons for a experiment. These totally immersed in 100ml 0.5M Hydrochloric acid (HCl) an open beaker placed water bath at varying temperatures 2-8hrs respectively. At every specified temperature time interval, the coupon specimen withdrawn from test solution, washed, dried reweighed. The weight loss being...

Inhibition of aluminium corrosion in 1.5M H 2 SO 4 solution the absence and presence ofChrysophyllum albidum fruit extract (CAFE) at temperature range 30 -60 o C was studied using weight loss thermometric techniques.The acts as an inhibitor acid environment.The inhibition efficiency increased with increase concentration but decreased temperature.The inhibiting effect Chrysophyllum could be attributed to some phytochemical constituents which is adsorbed on surface aluminium.The found obey...

The corrosion inhibition of aluminium in 2 M H SO 4 by millet starch was investigated using gravimetric technique at 35-65 O C and theoretical quantum chemical computations. results indicate that functioned as a good inhibitor for acid induced aluminium. It found increase efficiency the concentration dependent also addition potassium iodide increased inhibitive performance synergistically. Furthermore, mode adsorption process best modeled Langmuir isotherm all concentrations temperatures...

Preparation of a novel organically modified clay from spent oil base drilling mud (SOBM) that could serve as core-shell filler for polymers is herein reported. Due to the hydrophilic nature clay, its compatibility with polymer matrix was made possible through modification surface core sample 3-aminopropyltriethoxysilane (3-APTES) compound prior use. Fourier transform infrared (FT-IR) spectroscopy used characterize modification. Electron dispersive X-ray diffraction (EDX) and scanning...
