Ultrasound-Assisted Post-Pyrolysis Magnetization Of Microporous Biochar For Effective Removal Of Heavy Metals, Ronish Shrestha
Ultrasound-Assisted Post-Pyrolysis Magnetization Of Microporous Biochar For Effective Removal Of Heavy Metals, Ronish Shrestha
Honors Theses
Low cost and efficient adsorption of heavy metals from wastewater and thorough removal of adsorbent after water treatment have become the two essential needs for the commercial use of any adsorbent. Biochar (BC), the solid byproduct of pyrolysis with microporous carbonaceous structure, has been increasingly recognized as an efficient adsorbent for a vast number of pollutants. Magnetization, though eases the separation and reuse of BC, significantly reduces its adsorption capacity to a comparatively much higher extent. In this study, a hybrid post-pyrolysis magnetization was developed which sustained and even significantly increased the adsorption capacity of biochar. The process included i) …

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 …
