Abstract:
The physicochemical properties of gold nanorods were used to develop many methods and techniques of detecting heavy metals recently. In this paper, the feasibility of gold nanorods was studied to detect metal lead in agricultural soil. The effects of soil properties on the form change of lead in soil were explored by gold nanorod detection technology. The results showed that the humic acid significantly increased Pb mobility and ion state exchanging. It also increased the lead content of organic bound state and Fe-Mn oxides state. And the detection process by gold nanorods proved to be a more simple and convenient method.
