Effect of Reaction Time on Pb Removal from Allophanic Volcanic Ash Soil by Acid-washing

Proceeding of Chemistry Conferences vol.1(1) 2016: 10th Joint Conference on Chemistry

“…Indonesia as one of the most active volcanic countries in the world has abundant of Andisol land. Isoyama and Wada (2005) in their research mentioned volcanic Andisol soil containing allophane under acidic conditions have metal ion absorption of lead (Pb). Parfitt (2009) showed that physical and chemical characteristic of Andisol soil are well used as an adsorbent of heavy metal and pathogens.…”
