Abstract

In this study, methylene blue (MM) adsorption from aqueous solutions with magnetic NiFe 2O4/activated carbon nanocomposite synthesized by attaching NiFe2O4 nanoparticles to commercial activated carbon surface was investigated. Characterization of the synthesized magnetic NiFe2O4/activated carbon nanocomposite was performed with SEM, BET and FTIR devices. In adsorption studies; solution initial pH value, MM initial concentration, adsorbent amount and solution ambient temperature parameters were investigated. It has been found that the adsorption capacity increases with increasing initial concentration of the MM blue solution and time. Adsorption equilibrium data were found as Langmuir isothermic. The maximum adsorption capacity of Qmax was determined as 167.45 mg / g and the adsorption kinetics were determined as pseudo second order kinetic model.

Özet

Bu çalışmada, ticari aktif karbon yüzeyine NiFe2O4 nano parçacıklarının tutturulmasıyla sentezlenen magnetik NiFe2O4/aktif karbon nanokompoziti ile sulu çözeltilerden metilen mavisi (MM) adsorpsiyonu incelenmiştir. Sentezlenen magnetik NiFe2O4/aktif karbon nanokompozitin karakterizasyonu SEM, BET ve FTIR cihazları ile gerçekleştirilmiştir. Adsorpsiyon çalışmalarında; çözelti başlangıç pH değeri, MM başlangıç derişimi, adsorbent miktarı ve çözelti ortam sıcaklığı parametrelerinin etkileri araştırılmıştır. MM mavisi çözelti başlangıç konsantrasyonu ve zamanın artmasıyla birlikte adsorpsiyon kapasitesinin arttığı tespit edilmiştir. Adsorpsiyon denge verilerinin Langmuir izotermine uyduğu tespit edilmiştir. Maksimum adsorpsiyon kapsitesi qmax, 167,45 mg/g olarak belirlenmiş ve adsorpsiyon kinetiğinin yalancı ikinci derece kinetik modele uyduğu tespit edilmiştir.
