Data of heavy metals biosorption onto Sargassum oligocystum collected from the northern coast of Persian Gulf

摘要

This data article presents a simple method for providing a biosorbent from Sargassum oligocystum harvested from the northern coast of Persian Gulf, Bushehr, Iran. The characterization data of Sargassum oligocystum biochar (SOB) were analyzed using various instrumental techniques (FTIR and XPS). The kinetics, isotherms, and thermodynamics data of Hg²⁺, Cd²⁺, and Cu²⁺ ions onto SOB were presented. The maximum biosorption capacity of SOB to uptake Hg²⁺, Cd²⁺, and Cu²⁺ ions from aqueous solution was obtained 60.25, 153.85, and 45.25 mg/g, respectively. The experimental data showed that biochar prepared from Sargassum oligocystum is an efficient and promising biosorbent for the treatment of heavy metals-bearing wastewaters.
