Abstract:
Researchers at the Chemistry Department of Iran's Islamic Azad University managed to prepare dye-adsorbing nanocomposites based on wood waste and residue with potential use in wastewater treatment of the effluents from textile and dye industries.

Iranian Researchers Develop Low-Cost Nano Adsorbent for Dye Removal from Wastewater

Tehran, Iran | Posted on July 17th, 2012

During the recent years, there has been a surge of interest in the synthesis of new and environmentally friendly adsorbents based on low-cost and natural materials such as hulls and husk of agricultural crops, wood residues, pebbles, etc.

"Our research works have been mainly focused on developing inexpensive and efficient nano adsorbents. In this regard, we concluded sawdust as an excellent basis and applied the chemical co-precipitation method to synthesize CuFe2O4/sawdust nanocomposites (with copper and iron oxides and nano ferrite spinel the as raw materials)," Dr. Saeedeh Hashemian, member of the academic board of Islamic Azad University, Yazd Branch, explained.

"Subsequently, we evaluated the efficiency improvement due to the incorporation of sawdust in the prepared nanocomposite for adsorptive removal of cyanine acid blue (CAB) from aqueous solutions."

"The obtained results reveal that nano ferrite spinel particles have been deposited on the sawdust structures favorably and the yielded nanocomposite possesses a higher dye-removal efficiency compared to that of each of its components (i.e. sawdust and ferrite spinel) applied singly," she said, summarizing her comments regarding their experimental results.
