Adsorption and photocatalytic detoxification of diazinon using iron and nanotitania modified activated carbons

Original language description

Diazinon is used as an insecticide for different types of cultivation. It is considered to be a toxic pollutant. In this work, we present a comparative study of diazinon detoxification by two methods: adsorption and photocatalytic degradation. Chemically activated carbon (AC) was prepared from flamboyant pods. AC was modified with iron (Fe-AC) to be used as a solid adsorbent for diazinon. TiO 2 and TiO 2 -AC, as photocat- alysts for degradation of diazinon, were prepared by the sol-gel method. Textural and surface character- izations of the prepared solid samples were carried out using nitrogen adsorption at -196 °C, scanning electron microscopy (SEM), pH PZC and the Boehme titration method. Adsorption of diazinon was inves- tigated on AC and Fe-AC considering the effects of pH, time, adsorbent dosage and concentration. The results showed that the adsorption capacity of Fe-AC is three times higher than that of AC. Furthermore, as the adsorbent dosage increases, the diazinon removal percentage increases, and adsorption follows pseudo-first- and pseudo-second-order equations. The diazinon photocatalytic degradation efficiency for TiO 2 -AC is higher than that for TiO 2, the diazinon degradation percentage reaches 95% in the case of TiO 2 -AC and only 55% in case of TiO 2 after 80 min.
