A Team at the Nanoscience Program Develop Novel Magnetic Nanomaterial for Industrial Wastewater Purification
Textile industries produce a massive amount of wastewater that should be cleaned from toxic substances such as fats, colors, and any chemicals used during the production steps. Water-treatment methods should be facile, economic, fast, and efficient.
Alaa Shaaban, a third-year Nanoscience student, and Dr. Ahmed Saeed, an adjunct assistant professor in Nanoscience Program from Professor Ibrahim El-Sherbiny’s research group published a new paper reporting a novel magnetic adsorbent nanomaterial with a specific chemical modification that enables it from capturing organic dyes from industrial wastewater eluted from textile factories. The particle size of this adsorbent nanomaterial is about 0.01 of the diameter of the red blood cell and about 1/10 4 of the human hair width. One of the advantages of this new material is that it can be easily collected from water by applying an external magnetic field using a strong magnet after finishing the treatment process. Moreover, this new adsorbent material demonstrates excellent water purification efficiency of about 100% of the organic dye content in wastewater samples can be efficiently removed within 30 minutes at room temperature without any sample pretreatment. Furthermore, the work presents the first spectrophotometric analytical method for the simultaneous assay of two of the most commonly used organic dyes in textile industries, bromophenol blue, and bromocresol green. The work was published in the highly reputable journal, Spectrochimica Acta Part A, published by ELSEVIER.
