Research ArticleOpen accessEvery word in the titleEnhancing of Copper (II) Adsorption Efficiency by Mixing Plantain and Orange Peelings as Bio-Sorbent SupportSamomssa Inna, Ebelle Epoi Charlotte Alvine, Adjia Zangue Henriette, Sieliechi JosephThe present study focuses on the valorization of plantain and orange peels in the field of water treatment contaminated by heavy metals, especially copper (II). To carry out this study, simplex centroid mixture design was used to determine best mixture from plantain and orange peelings through iodine number, specific surface area and point of zero charge. The influence of contact … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 19 Oct 2020 · 6,920 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleTartaric Acid Modified Rice Hull as a Sorbent for Methylene Blue RemovalSiew-Teng Ong, Pei-Sin Keng, Ai-Wen Chong et al.Problem statement: Improper dye discharge from various industries such as textile, paper, cosmetic and plastics into receiving streams can be one of the sources towards water pollution. The release of these effluents not only causes various disruptions in the ecosystems, but also poses hazard effect as most of the dyes are highly toxic, mutagenic and carcinogenic in nature. Approach: To … …American Journal of Environmental Sciences, Vol. 6, Issue 3 · 30 Jun 2010 · 7,151 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleEquilibrium 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 PDF Cite
