Studding the effect of immobilization of Zinc dioxide nanoparticles based on diatomite adsorbent on the xylene adsorption capacity
Rapid growth of industries-has led to increase in occupational exposures to volatile organic compounds, so because of having adverse effects on humans, controlling of these compounds are essential. The aim of study was to compare the xylene adsorption capacity in two types of diatomite adsorbent with and without zinc oxide nanoparticles …..
After chemical and thermal modifying the diatomite by 1 M hydrochloric acid, absorption experiments were performed on two types of diatomite with nanoparticles zinc dioxide and without nanoparticles. Adsorption isotherms were investigated to evaluate the xylene adsorption capacity and to match them with the IUPAC model. Data analysis was performed by phocheck tiger device
By the BET analysis, it was found that diatomite with nanoparticle had less Special surface area than diatomite without it. SEM and EDX analysis indicate that ZnO particles are immobilized on the adsorbent. Xylene absorption capacity after modifying with nanoparticles increased from 1.64 to 2.6 mg / g, and breakthrough time after modification with nanoparticles decreased from 18 to 14 minutes.
The modification of diatomite with ZnO nanoparticles increases the absorbance capacity and it can be used as an appropriate catalyst for the removal of volatile organic pollutants.
