The content of lead and cadmium in the surface layers of intra-body implants based on α-Al₂O₃ and in their raw materials, was determined by extracting their aqueous solutions with 4% (v/v) acetic acid and Ringer's solution. The extracted metals in ionic form were determined electrochemically by differential pulse stripping voltammetry (DP ASV) at the hanging mercury drop electrode (HMDE). The method employed is used in optimizing the technology of preparation of impants and assessing their applicability in clinical practice. |
