Research ArticleOpen accessIn the abstractRemediation of Heavy Metals by using Industrial Waste by Products in Acid Mine DrainageNuur Hani Mohammed, Mustapha Atta, Wan Zuhairi Wan YaacubAcid Mine Drainage (AMD) is one of the main important problems being combated today. Laboratory tank experiments were conducted to evaluate the use of industry waste to adsorb and control the mobilization of metals from contaminated acid mine water. The main physical conditions such as pH and treatment performance are displayed. The solution of acid mine were sampled from the … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 18 Dec 2017 · 7,342 accessesView PDFCite
Research ArticleOpen accessIn the abstractEquilibrium Studies and Optimization of Phosphate Adsorption from Synthetic Effluent Using Acid Modified Bio-SorbentBabayemi Akinpelu Kamoru, Onukwuli Okechukwu DominicAdsorption potential of periwinkle shell (PRW), an agricultural waste, for the removal of phosphate from aqueous solution was investigated through equilibrium studies at various experimental conditions. PRW was carbonized and chemically activated with 1MH2SO4 before it was subjected to characterization using Fourier Transform Infrared (FT-IR), Energy Dispersive X-ray (EDX) and Scanning Electron Microscopy (SEM). Adsorption data were analyzed using various … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 15 Dec 2017 · 7,666 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiochar Types from Latrine Waste and Sewage Sludge Differ in Physico-Chemical Properties and Cadmium AdsorptionKoetlisi Andreas Koetlisi, Pardon MuchaonyerwaPyrolysis of latrine fecal waste could produce valuable products for minimizing environmental contamination with heavy metals. The objective of this study was to determine yields, characteristics and cadmium (Cd) sorption of biochar from latrine fecal waste and sewage sludge, as affected by pyrolysis temperature. Slow pyrolysis at 350, 550 and 650°C, was used to produce the biochar. In addition to … …American Journal of Applied Sciences, Vol. 14, Issue 11 · 30 Nov 2017 · 8,512 accessesView PDFCite
