This research reveals improved adsorption of cadmium and zinc in aqueous solutions using functionalized b-zeolite, indicating significant potential for water treatment.
Key Points
The functionalized b-zeolite exhibited a notable increase in adsorption capacity for both cadmium and zinc ions.
Adsorption capacity improved from 17.5 mg/g to 40.7 mg/g for zinc and from 21.2 mg/g to 62.3 mg/g for cadmium.
The kinetic analysis shows the adsorption follows a pseudo-second-order model, suggesting a chemisorption mechanism.
These findings highlight the effectiveness of modified b-zeolite as an adsorbent for heavy metal ion removal from contaminated water.
