Removal of methylene blue using iron oxide prepared through solid and wet solution route

Removal of methylene blue using iron oxide prepared through solid and wet solution route / Nur Aqilah Samsukamal
Dua jenis ferum oksida yang disediakan melalui kaedah keadaan pepejal dan kaedah larutan basah telah dicirikan dan diuji sebagai penjerap untuk penyingkiran metilena biru (MB) daripada larutan akueus. Sifat-sifat penjerap telah dicirikan menggunakan pembelauan sinar-X (XRD) dan pengukuran luas permukaan BET. Penjerap tersebut terdiri daripada ferum oksida (hematit). Kajian ini telah dijalankan untuk mengenalpasti kapasiti penjerapan penjerap dengan mengkaji kesan kepekatan awal pewarna (25-300 mg/L), masa sentuhan (0-24 jam) dan suhu larutan (30, 45 dan 60oC) terhadap penyingkiran pewarna MB. Walau bagaimanapun, oleh kerana data keseimbangan yang diperolehi bagi penjerapan pewarna MB tidak konsisten untuk semua parameter yang dikaji, keadaan ini menunjukkan bahawa ferum oksida yang dihasilkan dalam kajian ini tidak sesuai untuk digunakan sebagai penjerap bagi penyingkiran pewarna MB. Oleh itu, hasil yang optimum untuk penjerapan pewarna menggunakan penjerap tersebut tidak dapat ditentukan dalam kajian ini. _______________________________________________________________________________________________________ Two types of iron oxide prepared through two simple synthesis routes (i.e. solid state method and wet solution method) were characterized and tested as adsorbents for methylene blue (MB) removal from aqueous solution. The properties of the adsorbents were characterized by X-ray diffraction (XRD) and BET surface area measurement. The adsorbents composed of iron oxide particles (hematite). Experiments were carried out to determine the adsorption capacity of the adsorbents by studying the effect of initial dye concentration (25-300 mg/L), contact time (0-24 hours) and solution temperature (30, 45 and 60⁰C) on the removal of MB dyes. However, since the obtained equilibrium data for the MB dye adsorption was not consistent for all the studied parameters, it is suggested that the iron oxide is not suitable to be used as adsorbents for MB dye removal. Therefore, the optimum results for the dye adsorption using iron oxide adsorbents is unable to be determined.
