Enhancement of Electrical Conductivity of Laterite Derived Ferric Oxide to Facilitate As Anode Materials
Abstract: Laterite is a mineral abundant in ferric oxide and various impurities, including aluminum oxide and silicon dioxide. The extraction of ferric oxide from laterite is accomplished through a cost-effective leaching process employing HCl, NaOH, and Sodium dodecyl sulfate (SDS). Characterization using Xray diffraction (XRD) confirmed the synthesized particles to be α-Hematite nano particles, with an average particle size of 94.21 nm, predominantly falling within the range of 90 nm to …

Improved TOPSIS for Al-SiC Composite Material Selection
Abstract: This paper proposes a novel Multi-Criteria Decision-Making(MCDM) method for attaining accurate and reliable results on Al-SiC composite material selection. Many of the existing researches suggested some methods for determining weights for criteria objectively and dealt with various mathematical models for eliminating inter-criteria correlation. However, they still involve some considerable shortcomings not fitting in the reality. In this paper, in order to determine the weights of criteria, methods for both subjective …

Characteristics of Sulphate, Nitrate and Total Dissolved Solid on Packed Bed Treatment of Petroleum Hydrocarbon Contaminated Water Using Adsorbent
Abstract: The characteristics of sulphate, nitrate and total dissolved solid was monitored in treatment of water medium contaminated with petroleum hydrocarbon. Agro-based adsorbent was used at different operating temperature in a packed bed unit connected in series of 1, 2 and 3. The initial concentration of sulphate, nitrate and total dissolved solid was measured and after the contaminates had passed through each packed bed unit. The result shows that the adsorbent …
