The next event in the PhDTalks series will take place on Tuesday, November 11, in the Grandori room (Building 4), from 12:00 to 12:30 CET.

PhDTalks is a series of seminars and discussions among PhD students. The events aim to provide a space for networking among PhD students and connecting with the many projects developed within our department.

The speaker, Ashfeen Ubaid Khan, will give a seminar entitled “Multiscale Investigation of Iodinated Contrast Media Agent Removal Using Engineered Montmorillonite Clay.”

At the end of the event, a small refreshment will be available, funded by the department.

It will also be possible to attend the conference online at the following link.

Abstract
Iodinated contrast media agents (ICMs) are pharmaceutical compounds essential for medical imaging that escape into water systems, resist conventional treatment, and generate toxic byproducts. We present an engineered clay for targeted removal of these pharmaceutical contaminants, investigated through multiscale experiments spanning batch studies to continuous flow columns simulating real world conditions. Coupling experimental data with Bayesian modeling of adsorption dynamics reveals how the amphiphilic porous architecture of engineered clay achieves over 93% removal efficiency. This integrated approach of experimentation and modeling reveals both performance and the underlying mechanisms essential for deployable water treatment systems.

Speaker’s bio
Ashfeen has a background in Environmental Analytical Chemistry and his research with the H2020 Marie Skłodowska-Curie (European Industrial Doctorate) REMEDI project at Politecnico di Milano employs a multiscale approach to investigate the trapping, removal, and recovery of iodinated contrast media agents from environmental systems.
