Iranian researches used nanoparticles to synthesize a new type of absorbent to remove toxic dyes from textile industry wastewater with acceptable quality.
The entrance of the outlet fluids in textile industry to the environment is one of the important issues. The majority of the synthesized and natural dyes have complicated aromatic structure molecules, and they are resistant to microbial and decomposition agents in the environment.
The aim of this research was to present an efficient adsorbent to eliminate such pollutants from the outlet water of plants and industrial factories through a new method with high yield.
"In this project we tried to present a method in order to remove water pollutants, which can be used in water purification systems," Arezoo Amiri, one of the researchers of the plan, stated.
In this method, the effective parameters were firstly optimized. Next, the efficiency of the produced adsorbent was studied and compared to other adsorbents used for this purpose. Finally, the performance of the nanoparticle was confirmed.
Nanomaterials are important in chemical interactions due to their high specific area and the great number of available atoms. This fact increases the performance of the method and also increases the efficiency.
On the other hand, one of the most important and effective parameters in adsorption method is the ratio of area to the volume of the adsorbent. This ratio is very high in nanoparticles.
"Due to their specific characterizations, nanoparticles can increase the efficiency and performance of the methods. They can also reduce the time of the process. Therefore, the use of nanoparticles in this method is very cost-effective," Amiri added.
Results of the research have been published in Chemical Engineering Communications, vol. 200, issue 8, 2013. For more information about the details of the research, study the full paper on pages 1071-1088 on the same journal.
