The Removal of Cationic Dyes Using Coconut Husk as an Adsorbent
نویسندگان
چکیده
The ability of coconut husk to remove methylene blue from solution was investigated. Factors such as initial dye concentration, contact time, adsorbent dosage and pH of solution were studied. Results show that Langmuir isotherm can be successfully applied to the methylede blue coconut husk system and that coconut husk is a suitable adsorbent for such a dye. Maximum adsorption capacity is 99 mg gl moss as derived from Langmuir isotherm. A series offixed bed experiments was carried out and the results were applied to a bed-depth/service time modelfor column adsorption. The validity ofsuch a model is discussed.

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,...
