Inactivation of Ascaris eggs in water using hydrogen peroxide and a Fenton type nanocatalyst (FeOx/C) synthesized by a novel hybrid production process.
TL;DR: Inactivation tests of Ascaris eggs were performed using hydrogen peroxide and a Fenton type nanocatalyst supported on activated carbon (AC) (FeOx/C), showing an average Ae inactivation efficiency that is significantly higher than the result obtained using the support-H2O2 system and H1O2 alone and it is also better than data reported for the classical Fenton process with or without UV light.
