Enhanced microextraction kinetics: Sorptive-dispersive vs. conventional techniques on rotating disks

The kinetic comparison clearly shows that RDSDE is a more efficient extraction technique due to its rapid extraction equilibrium. The dispersive mechanism plays a crucial role in accelerating analyte extraction, as evidenced by the steeper extraction profiles of RDSDE compared to RDSE. Importantly, this study presents the first direct kinetic comparison between RDSDE and conventional RDSE, highlighting the novelty of the approach. This underscores the potential of RDSDE as a faster and more efficient method for extracting target compounds from aqueous samples, offering significant advantages in analytical performance and operational efficiency.
