Ultrasonic-assisted synthesis of g-C3N4/Clinoptilolite composite: Efficient adsorption of methylene blue

The adsorption method is one of the methods used due to its high efficiency, low cost, convenience and simplicity. In the present research, Graphitic carbon nitride/clinoptilolite (g-C3N4/CP) was synthesized based on the ultrasonic method. Typicaly, 16 g of urea was stirred in 50 cc of deionized water for 15 min. Then 1 g of Clinopetilolate was added to the above solution and subjected to ultrasonic for 30 min. The solution was dried in an oven at 80°C for 12 hr and finally calcined in the oven at 550°C for 2 hr. The XRD pattern of the g-C3N4/CP composite and the FT-IR spectrum show that the composite is correctly synthesized. Adsorption of methylene blue (5 ppm) by synthesized composite (0.3 g/l) was invesitigated for 180 min. Methylene blue absorption efficiency for bulk g-C3N4 and g-C3N4/CP composite was 16.3 and 60.9%, respectively, and the absorption capacity was 0.47 and 2.23 mg/g. The presence of clinoptilolite has improved the methylene blue absorption performance.
