摘要：
4-Bromo-1, 8-naphthalic anhydride and N, N-Dimethylethylenediamine covalently modified silica nanoparticles were synthesized. It can be utilized as an adsorbent for Pb (II), showing excellent adsorption capacity. According to the Langmiur fitting, the maximum adsorption capacity for lead ion is up to 293.26 mg/g. And the adsorption percentage is greater than 90 % when the initial concentration is lower than 100 mg/l.
