Novel Modified ZSM-5 as an Efficient Adsorbent for Methylene Blue Removal

Modified zeolite adsorbent (SuZSM) was prepared by impregnating ZSM-5 (Zeolite Socony Mobil–5) with sugar solution followed by carbonization in nitrogen environment. Synthesis of nanoscale zero-valent iron (NZVI) was carried out by reduction method. NZVI then was supported by both unmodified ZSM and...
