The influence of pH solution on the value of heavy metals ions adsorption at the surface of dielectrics

The influence of pH solution on the value of heavy metals ions adsorption at the surface of dielectrics was established. It was showed, that the adsorption value of Pb+2, Zn+2 and Cd+2 is minimal in the range of pH>7 and maximal in the range of pH<7 for all sort of glass. In case of the adsorption process at the surface of quartz and teflon unique dependence was not observed. However, the range of pH in which the adsorption value of Pb+2, Zn+2 and Cd+2 is maximal was established.
