Study on Biosorption of Divalent ion onto Treated Prosopis Juliflora Bark from Aqueous Solutions: An Approach towards Isothermal and Statistical Analysis | Chapter 3 | Challenges and Advances in Chemical Science Vol. 3

 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.

Study on Virtual Screening of Treated Pistachio vera Shell Powder as a Potential Sorbent in Sequestering Ubiquitous Divalent Metal Ions from Aqueous Matrices | Chapter 2 | Challenges and Advances in Chemical Science Vol. 3

 Water contamination caused by poisonous heavy metals such as Hg(II), Cr(VI), Cd(II), and Pb(II) ions, among others, has gotten a lot of attention recently. Because of their toxicity, accumulation, and biomagnification, increasing quantities of heavy metals in the ecosystem poses a serious health risk. Lead pollution of drinking water is a serious concern due to lead pipes, plating units, and other sources. A firm covering surrounds the nut kernels in the pistachio vera shell (PVS). The current study examines the feasibility of powdered Pistachio vera shell (PVSP) - a bio waste - in sequestering Pb(II) ions after being treated with 0.1N HCl / NaOH to improve sorption efficacy (TPVSP). For material characterization, SEM, FTIR, and microscopic studies are recorded. The sorbent material's competence is experimentally verified in Batch mode under a variety of operating conditions, including particle size and dosage of TPVSP, agitation time interval between TPVSP and Pb(II) ions, initial concentrations of Pb(II) ions, pH of the adsorption medium, effects of cations, anions, and co-ions, and temperature influence on the Pb(II) – TPVSP system. Atomic Absorption Spectrophotometer is used to determine the residual amounts of Pb(II) ions in aqueous solutions (SHIMADZU-AA-6200). The adsorption capacity is described using the Langmuir and Freundlich models. To ensure the quantitative estimate of TPVSP, column experiments are undertaken, in which 40 mg TPVSP at a flow rate of 100 ml/10 mins removes 99 percent of Pb(II).
