摘要：

Ever-growing application of engineering nanoparticles in many sectors of the society requires efficient methods to extract them from soil and sediment, for the sake of environmental protection. In this study, we develop a new method which uses sodium pyrophosphate solution (TSPP, Na4P2O7) as extratant to extract gold nanoparticle (AuNPs) from soil and sediment under optimized parameters through vortexing, water bath oscillation, ultrasonic bath and precipitation. SP-ICP-MS was used for the detection of number concentration, mass concentration a...
