Zeolite 4A-Modified MgAl 2 O 4 /CuFe 2 O 4 Ceramic Nano-composite to Eliminate Methylene Blue from Aqueous Solutions

Zeolite 4A-modified MgAl2O4/CuFe2O4 magnetic ceramic nanocomposite was utilized as an efficient adsorbent to eliminate methylene blue (MB) from aqueous solutions. The influence of zeolite 4A weight percentage (from 5 to 50 wt%) was investigated on the M B removal efficiency. To determine the characterization of specimens, several analyses including Brunauer-Emmett-Teller (BET), Barrett-Joyner-Halenda (BJH), field emission scanning electron microscopy, energy dispersive X-ray, Fourier transform infrared, X-ray diffraction and v ibrating sample magnetometer were performed. The optimal conditions for the adsorption of M B dye were recognized as 45oC temperature, 0.2 g adsorbent dosage, 30 mg/L initial MB concentration, 25 min contact time and pH of 11. The maximum adsorption capacity and removal efficiency on the nanocomposite were 29.32 mg/g and 99.8%, respectively.
