Removal of Cesium Ion from Aqueous Solution using Allophane

Batch experimental studies of Hg(II) ion removal from aqueous solution using seven synthetic polymers

In this work application of seven synthetic polymers as adsorbents for the removal of Hg(II) from aqueous solution was studied. The equilibrium studies are systematically carried out in a batch process, covering various process parameters that include agitation time, adsorbent dosage, and pH of the aqueous solution. Variations of Hg(II) concentration in solution have been studied through measur...

Efficient removal of cobalt(II) ion from aqueous solution using amide-functionalized metal-organic framework

In this study, an amide-functionalized metal-organic framework, namely TMU-24 was selected to adsorb Co(II) from wastewater with an adsorption capacity of 500 mg. g-1 in less than 20 minutes in neutral pH (pH=7). The effect of diverse parameters such as adsorbent dosage, competitive ions, and contact time on the adsorption process was investigated to find the optimal amounts of them. Also, the ...

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,...

Arsenic 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...
