The uptake properties of the metals were found to be related to the zeta (ζ) potential profile of ETS-10 and the characteristics

Heavy Metal - an overview | ScienceDirect Topics

Heavy metals are generally referred to the metals with relatively high atomic weights in the range of 63.5–200.6 g mol −1 and the densities more than 5 gr cm −3 (Srivastava and Majumder, 2008). Although the body requires low amounts of some heavy metal ions such as Zn 2+ , Mn 2+ , Fe 2+ , Cu 2+ for growth and body health, high levels of them are toxic ( Valko et al., 2005 ).
