Graduate student teaching at the College of Marine Sciences, Salah Mahdi Saleh, discussed his thesis titled (Extraction and removal of dyes from their aqueous solutions using the solid phase extraction technique (SPE) using multi-walled carbon nanotubes (MWCNTs) and their derivatives)
Extraction and Removing of Dyes from Aqueous Solution by SPE Method Using MWCNTs and their Derivatives
The thesis discussed the chemical preparation of multi-walled carbon nanotubes and their derivatives and their use as extraction surfaces for the positive Bismarck Brown-Y and Orange-G dyes in the solid phase extraction technique. The study also concluded the effectiveness of these prepared surfaces in removing pollutants. The study recommended the possibility of using these surfaces in Other techniques, such as point cloud extraction and other extraction methods. The discussion committee recommended accepting the thesis and grading it with distinction. Note that the discussion took place in the College of Science, Chemistry Department.
