A comparative study of malachite green removal from an aqueous solution using raw and chemically modified expanded perlite
Adsorption of malachite green (MG) from an aqueous solution onto unexpanded perlite (UP), expanded perlite (EP) and NaOH-modified unexpanded perlite (NaOH-UP) powders has been investigated. The effects of contact time, pH, initial dye concentration, adsorbent dosage and temperature have been evaluated. The adsorbents were characterized by Brunauer-Emmett-Teller (BET) analysis, Fourier transform...
متن کاملAdsorption of Lead from Aqueous Solution by Modified Beech Sawdust
Sawdust is now being investigated as an adsorbent to remove contaminants from aqueous solution. Heavy metals can be decreased very effectively with the organic material. In this research, adsorption of Pb (II) onto modified beech sawdust in a batch system was investigated. Sawdust was collected from timber mill of Qom, Iran, and modified with H2SO4 and NaOH. Then, the effe...
متن کاملAdsorption kinetics and thermodynamics of Malachite Green from aqueous solutions onto expanded Graphite nanosheets
Expanded graphite nanosheets (EG-nanosheets) were used for adsorption of Malachite Green (MG) from aqueous solution. The influences of dye concentrations, absorbent dosage, pH values and the temperatures on the adsorption were investigated as well. The dye adsorption experiments were carried out by utilizing batch procedure. EG-nanosheets were initially characterized by scanning electron micros...

متن کاملAdsorption of Lead from Aqueous Solution onto Untreated Orange Barks
Waste materials with no further treatment such as orange barks from commercial oranges may act as adsorbent for the removal of Pb. Batch kinetic and equilibrium experiments were conducted to study the effects of contact time, initial pH, adsorbent dose and initial concentration of lead. The results show that the equilibrium was achieved less than 30 min of contact time. Three adsorption isother...
