Abstract
Magnetite(Fe3O4) nanoparticles are used in nanotechnological applications and removal of heavy metals from wastewater. This study investigated the influence of synthesis conditions on the size and shape magnetite(Fe3O4) nanoparticles for the removal of heavy metals. Magnetite size is influenced by synthesis temperature, NH4OH concentration, pH and the atmosphere(O2 and N2). We synthesized the magnetite in two ways. One is by pouring the NH4OH solution(M1) and the other is by injecting in 6 ml/min(M2). Magnetite-M1 and M2 size was 13.58, 8.8 nm. From the Langmuir isotherms, the maximum adsorption capacities towards Cu were Magnetite-M1: 17.04 mg/g and Magnetite-M2: 21.07 mg/g. That data shows the synthesized Magnetite by putting NH4OH solution(6 ml/min) is more property to remove heavymetal from wastewater.
