This study presents a new iterative deblending method to separate Active Galactic Nuclei (AGN) from host galaxy emission in integral field spectroscopy (IFS) data. The method models the spatial brightness of both the AGN (as a point source) and the host galaxy (as a Sersic profile) in each spectral slice, requiring no prior PSF knowledge. Validated with mock observations and MaNGA data, the technique accurately recovers AGN and host spectra, emission line properties, and star formation diagnostics using BPT diagrams, improving analysis of AGN-host interactions.
