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 PDFCite
Research ArticleOpen accessEvery word in the titleDynamic Measurement of Copper (II) Ion Adsorption in Activated Carbon Fixed Bed ColumnsTanokkorn Banjonglaiad, Eric Croiset, Peter Silveston et al.Dynamic experiments were carried out on the adsorption of copper (II) ions in a laboratory packed bed of activated carbon. Both pulse and step change inputs were used. Measurements were reproducible and replicate measurements furnished nearly identical parameters for a heterogeneous model of the activated carbon bed assuming Langmuir adsorption isotherm. The initial concentration of copper (II) ion was 3 … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 6,862 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRemoval of Copper from Aqueous Solution using Tunisian ClayN. Boujelben, S. Gharab, F. Bouhamed et al.Natural adsorbents such as clay was used to replace expensive imported synthetic adsorbents. In this study, Scanning Electron Microscopy (SEM), Infrared spectroscopy and X-ray diffraction techniques were used to characterize the used sorbent (clays C). Batch experiments were performed to evaluate the effects of contact time, solution pH and temperature on copper removal onto used sorbent from aqueous solution. Equilibrium … …American Journal of Environmental Sciences, Vol. 11, Issue 2 · 15 Jun 2015 · 7,182 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEnergetic Aspects Related to Heavy Metals Adsorption on the Surface of Volcanic Tuff I. The Influence of Activation Parameters in Cu2+ AdsorptionLeonard Mihaly-Cozmuta, Teodor Visan, Anca Mihaly-Cozmuta et al.The article develops some physico-chemical aspects presented along of copper ions adsorption in treatment of wastewaters using volcanic tuff. In the experiments volcanic tuff from Stoiana Pâglişa (Romania) has been used. Different concentrations of NaCl and HCl solutions were used for activation of tuff. The increase of activation solutions' concentrations indicates an intensification of specific adsorption of copper as consequence … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 6,666 accessesView PDFCite

Bentonite activation treatment performed. The parameters studied in this research is a variation of the mass of bentonite, contact time and adsorption capacity. Measurements were made using AAS. Activation of bentonite using a solution of HCl 1.6 M. In experiments conducted bentonite … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 25 May 2018 · 8,655 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Exhaust Gas Temperature on the Performance of Automobile Adsorption Air-ConditionerAbdul Hadi N. Khalifa, Ali H. Jabbar, Jamal A. MuhsinAn adsorption air conditioning unit of two beds was designed and built. Each bed was constructed from two concentric copper pipes sets, the length of the pipes in each set was 1500 mm pipe. The inner pipe was 50 mm in diameter while the outer pipe was of 100 mm diameter. The inside surface of the outer pipe and the … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 13 Oct 2015 · 8,083 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreparation-Properties Relation of Mn-Cu Hopcalite CatalystArdita Mele, Ilo Mele, Altin MeleProblem statement: The Mn-Cu hopcalite catalyst was used for the conversion of CO to CO2 at low temperatures.

Research ArticleOpen accessIn the abstractKinetic Study of the Effect of Selected Surfactants on Corrosion of CopperHowaida M. El-KashlanThe rates of copper corrosion were determined by measuring the limiting current of anodic dissolution of copper in phosphoric acid in presence and in absence of cetyl trimethyl ammonium bromide (CTAB) and cetyl pyridinium bromide (CPYB). The rate of corrosion is found to decrease by increasing the concentration of the surfactant. The percentage of inhibition ranged from 1.85 to 33.97% … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,137 accessesView PDFCite
