reaction of metals in calcium potassium iron in greece


2015-10-7 · Common heavy metals include cadmium, lead, nickel, cobalt, zinc, and chromium (Mojiri, 2011). Heavy metals are the unique class of toxicants because they cannot be fragmented down to non-toxic forms (Waoo et al., 2014). Literature states that not more than 10% of the metals in dumpsite leachate are free metal ions (Chaari et al., 2011).
