Using terahertz time-domain spectroscopy (THz-TDS), the optical parameters and the degree of regeneration of porous corundum ceramic filters employed for water and air purification have been investigated. For the samples studied, the regeneration efficiency, estimated from the relative decrease in the RMSD of the absorption coefficient spectra, amounted to 51%. For the regenerated sample, the refractive index in the terahertz range (n≈1.93) was determined, and a thickness map of the organic deposit was constructed. The work demonstrates the potential of THzTDS for nondestructive testing of ceramic filters and for assessing the quality of their regeneration.
