Study on Biosorption of Divalent ion onto Treated Prosopis Juliflora Bark from Aqueous Solutions: An Approach towards Isothermal and Statistical Analysis

August 31, 2021 Chemical Science 0

The current study focuses on the use of Prosopis juliflora bark for Cu adsorption (II). To improve sorption effectiveness, raw Prosopis juliflora bark is treated with 0.1N hydrochloric acid. Scanning Electron Microscopy, Energy Dispersive X-ray Analysis, Bruner-Emmet-Teller, and Barrett-Joyner-Halenda studies were used to characterise TPJB. The maximum amount adsorbed was found to be 43.11 mg/g (97.4%) during experimental verification for Cu(II)- TPJB in Batch mode under operating factors such as particle sizes/doses of the material upon a range of initial Cu(II) concentrations at different temperatures, agitation time, and pH values system, where the maximum amount adsorbed was found to be 43.11 mg/g (97.4%). Its efficiency was three times higher under optimal conditions than Ce levels reported by other researchers. Column studies are used to quantify treated Prosopis juliflora bark, and 98 percent Cu(II) removal is detected. For the Cu(II)-TPJB system, Langmuir, Freundlich, and Tempkin isothermal curves at various initial concentrations are plotted; the straight line fit is optimal for the Freundlich model. The effect of various parameters on the reaction of treated Prosopis juliflora bark in trapping Cu(II) ions is statistically confirmed using SPSS software, indicating good correlation.
