Indonesia Natural Mineral For Heavy Metal Adsorption: A Review, Grandprix T. M. Kadja, Moh Mualliful Ilmi

Journal of Environmental Science and Sustainable Development

Indonesia has abundant mineral resources used as natural adsorbent materials for the absorption of heavy metal. Among these are natural zeolites, clay, and ashes. These natural materials showed high performance adsorption capacity with respects to their low cost and high availability. Several research reports had been published for studying the performance of the natural materials as adsorbent of several heavy metals i.e., Hg, Pb, Fe, Cd, Cr, Zn, Ni, and Cu by examining the effect of various factors, including pH, contact time, initial concentration, temperature, and dosage. Furthermore, to determine the adsorption rate, mechanism, and efficiency of natural materials in …


Adsorption Of Heavy Metal Ions By Oil Palm Decanter Cake Activated Carbon, Mohd. Ezreeza Mohamed Yusoff, Juferi Idris, Nahrul Hayawin Zainal, Mohamad Faizal Ibrahim, Suraini Abd-Aziz Aug 2019

Adsorption Of Heavy Metal Ions By Oil Palm Decanter Cake Activated Carbon, Mohd. Ezreeza Mohamed Yusoff, Juferi Idris, Nahrul Hayawin Zainal, Mohamad Faizal Ibrahim, Suraini Abd-Aziz

Makara Journal of Technology

Adsorption processes are widely used for the removal of heavy metals from waste streams. Oil palm decanter cake (OPDC) is used as a bioadsorbent because of its compositional properties for activated carbon production; moreover, it is a readily available raw material produced in palm oil mills and is thus abundant and cheap. In this study, the OPDC was carbonized at 700 °C and activated using steam at 700 °C to produce oil palm decanter cake activated carbon (AC-OPDC). Batch adsorption experiments were carried out to compare the adsorption capacities of the raw OPDC and the AC-OPDC for heavy metals removal. …
