Sorption of Pb (II), Cd(II) and Zn(II) by synthesized nanocrystalline sodium potassium flurophlogopite (FGP)
Abstract: We have successfully synthesized nanocrystalline sodium potassium fluorophlogopite (FGP) crystals with controlled sizes from ≈ 25 nm to 100nm, using an organic tetrapropylammonium (TPA) hydroxide. We have been successfully synthesized material depends on the source of silicate and hydrothermal crystallization conditions. The synthesized materials were characterized by using different techniques such as X-ray diffraction, Energy Dispersive Analysis, Scanning Electron Microscope, Transmission Electron Microscopy and FTIR analysis. The use of sodium …

Iron Pillared Clay for Sorption of Toluene in Aqueous Solution: Kinetics and Equilibrium Studies
Abstract: The adsorption of toluene using unmodified and Fe-pillared clay were investigated in this study using UV/Visible, FT-IR spectroscopic measurements and batch adsorption process. The framework vibration of the clay before and after pillaring were determined using FTIR spectra. Effect of Contact time and initial and various concentration of toluene at constant temperature were investigated. The experimental data were studied using equilibrium isotherm (Langmuir and Freundlich) and kinetics models (pseudo first …

Lead (II) Ion Biosorption from Aqueous Solution ontoHexadecyltriammonium Bromide (HDTMA-Br) Modified Dry Water Hyacinth
Abstract: Heavy metal release into the environment by industrial activities has become a persistent problem,with these contaminants continually increasing in concentration. Heavy metals not only circulatethrough ecosystems but also accumulate in organisms over time, which elevates their toxic effectsalong the food chain. This research was conducted to explore the efficiency of biosorption inremoving lead (II) ions from aqueous solutions using water hyacinth powder modified withhexadecyltriammonium bromide (HDTMA-Br), a cationic surfactant. The …

Application of Agro-Residues for Removal of Oil Spill From Sea Surface
Abstract: Rice husk (RH), wheat straw (WS) and sawdust (SD) were studied for sorption of oil spill (diesel oil of density 0.828 g/cc was taken as oil spill for lab study) from artificially prepared sea water (3.5% NaCl) at 20, 25, 30 and 35°C at various dosages. As RH gave maximum sorption capacity at all temperatures and at all dosages under study, it was focus of investigation for its application for …

Application of Acid Treated Carbon Derived from Biomass (Lantana camara) for Removal of Phenol from Aqueous Solutions
Abstract: The presence of phenolic compounds is toxic and harmful to human health and aquatic life. Five biomass: cotton stalk, rice straw, bagasse, wheat straw and Lantana camara were characterized. Based on characterization and availability, Lantana camara (LC) was selected for study as an adsorbent. LC and activated Lantana camara (ALC) were further characterized and studied for their suitability as the commercial adsorbent for removal of phenol. Equilibrium study on ALC …

THERMODYNAMICS OF HEAVY METALS (Hg2+, Cd2+, Fe2+AND Ni2+) ADSORPTION USING BOILER FLY ASH
Abstract: The effect of temperature on the adsorption of heavy metals, Hg2+, Cd2+, Fe2+ and Ni2+ using unactivated boiler fly ash (an agricultural waste) was investigated. The results showed that Hg2+ and Cd2+ ions were mostly affected by increase in temperature because their sorption rate decreased at high temperature. At the temperature of 273 K and 383 K, the amount of Hg2+ adsorbed (mg/g) by the unactivated boiler fly ash was …

Mass Transport of Heavy Metals in Soil Columns Amended with Biochar Nanoparticles
Abstract: Biochar has potential as a valuable material for removing heavy metals from wastewater. The biochar obtained by pyrolysis of the Pomegranate Peel (PPBC) under an oxygen-limited atmosphere in a muffle furnace at 450°C. The biochar was also analyzed through SEM and FTIR for identification of particle size and functional groups. Therefore, the present work aims to study the effect of adding biochar to the soil columns (10 cm length and …

Preparation and Characterization of Ce-Si-SBA-15 Modified With Iron
Abstract: Recently environmental concerns have driven the development of specialized catalysts to prevent polluting substances from being released into the environment. New technologies have improvised our understanding of catalytic functions as well as selectivity in order to save the energy and chemicals. Today, catalysis is the workhorse in the chemical industry with approximately >90% of the products produced in catalytic processes. In addition, life cannot exist without catalysis, as virtually all …

Physical and Chemical Adsorption and its Applications
Abstract: The content of the review requires extensive information about the excellence of its physical and chemical types, which is a superficial phenomenon that refers to the ability of solid or liquid materials to attract or pull molecules of gases or liquid solutions to their surface to come into direct contact with them, where the term adsorbents is used to denote those solid or liquid materials. The liquid used to adsorb …
