Adsorption of Thorium(IV) on Chemically Modified Amazon Clays
Amostras de caulinita e esmectita oriundas da região Amazônica, Brasil, foram modificadas com 2-mercaptobenzimidazol (MBI) usando rotas homogênea e heterogênea. As amostras de argilas modificadas (K HOM, S HOM , K HET e S HET ) foram caracterizadas por análise textural, MEV e espectroscopia C NMR. As argilas modificadas quimicamente apresentaram modificações em suas propriedades físico-químicas...
متن کاملOptimization of Crystal Violet Adsorption by Chemically Modified Potato Starch Using Response Surface Methodology
In this research, a response surface methodology (RSM) was used to investigate the effects of independent parameters (pH, contact time, temperature, adsorbent dosage, and initial concentration of pollutant), their simultaneous interactions, and quadratic effects on crystal violet adsorption onto two starch based materials in the form of batch experiments. The characterizing results indicated th...

متن کاملEffect of Solution pH on the Adsorption of Paracetamol on Chemically Modified Activated Carbons.
Paracetamol adsorption in acidic, neutral and basic media on three activated carbons with different chemistry surfaces was studied. A granular activated carbon (GAC) was prepared from coconut shell; starting from this sample, an oxidized activated carbon (GACo) was obtained by treating the GAC with a boiling solution of 6 M nitric acid, so to generate a greater number of oxygenated surface grou...
متن کاملInfluence of Exchangeable Cations on Water Adsorption by Soil Clays
little is known about the molecular mechanisms of soil– water interactions underlying this behavior. A considerThe interaction of water with the clay fractions ( 2 m) from two able amount of work has been conducted on specimen midwestern soils was studied using Fourier transform infrared (FTIR) spectroscopy and gravimetric methods. The soil clay fractions were clay minerals and their interactio...
