    This work describes a rapid easy‐to‐use electrochemical method for quantifying lead (Pb2+) adsorption on metal oxide nanoparticles (NPs), demonstrated here for titanium dioxide (TiO2). The method was able to quantify Pb2+adsorption for concentrations as low as 0.95 μM, and up to 200 μM in NP dispersions, and to differentiate ion uptake in the presence and absence of a natural organic material, humic acid (HA). The method was selective for Pb2+against Cu2+, As3+, Zn2+, Cd2+and Cr3+ions when measured in the specific potential range from −0.4 to −0.6 V and was successfully demonstrated in water and home‐collected dust.
