Activated Carbon Prepared from Eichornia Crassipes as an Adsorbent for the Removal of Dyes from Aqueous Solution

The ability of the activated carbon prepared from Eichornia Crassipes to remove Reactive Magenta B and Reactive Turquoise Blue dyes from aqueous solution has been carried out as a function of contact time, dose (0.1-0.60 mg/50ml for Magenta B and 0.25-2.0 mg/50ml for Turquoise Blue), pH (2-10) and concentration (25, 50, 75, 100mg.L). An amount of 0.6 g of the adsorbent could remove 56.0% of the...

Amine Functionalized Kit-6 Mesoporous Magnetite Nanocomposite as an Efficient Adsorbent for Removal of Ponceau 4R Dye from Aqueous Solutions

In this study, amine functionalized Kit-6 silica mesoporous magnetite nanocomposite (NH2-MMNC) was synthesized by chemical methods and used as an efficient and recoverable adsorbent for removal of Ponceau 4R, as a toxic dye, from aqueous solutions. The synthesized nanocomposites were characterized by XRD, FT-IR, BET and SEM instruments. The effect of various experimental parameters on the dye r...

Using Generation 3 Polyamidoamine Dendrimer as Adsorbent for the Removal of Pentavalent Arsenic from Aqueous Solutions

Introduction: Arsenic is known as a carcinogenic compound in drinking water. It can cause acute and chronic effects on human health. In this study, the effect of polyamidoamine dendrimer generation 3 (PAMAM G3) as adsorbents for removal of arsenic (V) from aqueous solutions was evaluated. Materials and Methods: Adsorption experiment was studied in batch system and the effect of different varia...
