Dataset Information

Data on the removal of metals (Cr³⁺, Cr⁶⁺, Cd²⁺, Cu²⁺, Ni²⁺, Zn²⁺) from aqueous solution by adsorption using magnetite particles from electrochemical synthesis.

ABSTRACT: Magnetic materials are promising adsorbents for removing heavy metals from polluted wastewaters. Magnetite particles were prepared by electrolytic synthesis (average crystallite size 37.9±1.2 nm , surface area = 17.2 m 2 g - 1 , isoelectric point = 6.3, magnetic saturation = 62 emu g^-1) and used as adsorbent of heavy metals in aqueous solutions. The adsorption capacity of the magnetite was highly dependent on pH value, for Cd⁺², Zn⁺², Ni⁺² and Cu⁺² the removal performance was higher that 80% at pH = 8. For Cr+6, the acid pH showed removal percentage higher that 90%. The adsorbent was separated from the system, reactivated and reused in subsequent tests using batch adsorption. It was found that removal efficiencies were higher th
