Effective Removal of Methyl Orange Dyes Using an Adsorbent Prepared from Porous Starch Aerogel and Organoclay

Removal of Reactive Dyes (Green, Orange, and Yellow) from Aqueous Solutions by Peanut Shell Powder as a Natural Adsorbent

Abstract: Background & Aims of the Study: Textile dyes generally are made of synthetic, organic, and aromatic compounds that may be contain of some heavy metals in their structure. Complex structure and presence of these metals cause toxicity and may be mutagen, teratogen or carcinogen. This study has investigated the ability of peanut shell powder to removal of some reactive dyes (Green 19...

Removal of pollutant heterocyclic dyes from water with ZnO adsorbent

In this study, Copper oxide as a good and inexpensive adsorbent has been introduced and used for the removal of erythrosine and red carmoisine dyes from several water solutions successfully. The effect of various parameters such as pH, dye concentration, amount of adsorbent, contact time and temperature on removal processing was investigated. Adsorption isothermal data could be interpreted by t...

Removal of perilous dyes from aqueous solutions with CuO adsorbent

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...

Removal of Methyl Orange Dye from Aqueous Solution by a Low-Cost Activated Carbon Prepared from Mahagoni (Swietenia mahagoni) Bark

This study utilized Swietenia mahagoni bark–a wood processing industry waste, for the preparation of activated carbon, and then investigated for the removal of methyl orange (MO) dye by the Swietenia mahagoni bark activated carbon (SMBAC). The effect of pH (3–10), adsorbent dose (1–30 g/L), initial MO dye concentration (10–100 mg/L), and contact time (1–240 min) were evaluated...
