Removal of Cationic Dyes from Aqueous Solution using Organomodified Nanoclay
In this work, organomodified nanoclay has been used as the adsorbent for the removal ofbasic blue 41, cationic dye from an aqueous solution. The performance of the organomodified nanoclay was tested in a batch system under varying pH (2–12), adsorbent dosage (0.1–2 g L-1), initial dye concentration (10–60 mgL-1), and contact time (5- 100 min). The best conditions were achieved at pH of 7,...
متن کاملRemoval of Heavy Metals from Aqueous Solution by Mordenite Nanocrystals
This study examined the ability of the synthetic mordenite nanocrystal to remove Tl(III) and As(III) from an aqueous solution. The determination of the concentration changes of H+ and OH- quantities in the acidic (pH 3) and alkali (pH 9) treated mordenite nanocrystals were done by the potentiometric titration curves. The maximum uptake capacities (Qmax) of these metal ions using the mordenite i...
متن کاملArsenic Removal from Aqueous Solution Using Titanium Dioxide Nanoparticles (Anatase)
Background and Objectives: Groundwater sources, as strategic sources of water supply, are of particular importance for human beings. Arsenic is a toxic and carcinogenic contaminant that has been reported to be widely found in groundwater sources. In recent years, adsorption property of nanoparticles has been used to remove arsenic. The present study was performed with the aim of assessing the a...
متن کاملNitrate Removal from Aqueous Solution by Using Modified Clinoptilolite Zeolite
Background & Aims of the Study: Nitrate is one of the most important pollutants that its reduced form, nitrite, can cause serious problems for human health and environment. Adsorption with cheap sorbents such as Zeolite is the best way for removal of this pollutant. So this study aimed to apply modified Clinoptilolite Zeolite for nitrate removal. Materials & Methods...
متن کاملRemoval of Fe from Aqueous Solution by Natural Apatite
The feasibility of natural apatite for adsorptive removal of Fe from aqueous solution was investigated. Batch experiments were performed as function of process parameters such as contact time, initial concentration of Fe, temperature, apatite dosage and pH. The natural apatite exhibited a high performance for the removal of Fe from aqueous solution. The pH value clearly affects the removal mech...
