Naphthalene Removal From Water by Novel Mesoporous Carbon Nitride Adsorbent

S. E. Moradi

In the present work, well ordered, mesoporous carbon nitride (MCN) sorbent with uniform mesoporous wall, high surface area and pore volume has been fabricated using the simple polymerization reaction between ethylene diamine and carbon tetrachloride in mesoporous silica media. The structural order and textural properties of nanostructured materials were studied by XRD, elemental analysis, and nitrogen Adsorption–desorption experiment. Adsorption of naphthalene over various porous adsorbents such as mesoporous carbon (MC), mesoporous carbon nitride (MCN), and amino modified mesoporous carbon (AMC) was studied from solutions with different concentration at ambient temperature (28 ± 2 °C) and pH 7.5 in polar (water) solvent. The adsorption isotherms of naphthalene were in agreement with a Langmuir model, moreover, the uptake capacity of naphthalene over MCN was much higher than amino modified mesoporous carbon (AMC) and pristine mesoporous carbon adsorbent.
