Particulate-bound metal species, sequential

TABLE 11.11. Selected Sequential Extraction Schemes Commonly Used for the Fractionation of Particulate-Bound Metal Species (Post-1979) ... 

In the case of solid environmental materials such as soils, sediments or indeed suspended particulates the use of selective chemical leaching methods can provide some basic information regarding the nature of the radionuclide species bound to the solid matrix. A typical sequential leaching might follow a procedure similar to that suggested for the study of trace metal binding to sediments by Gupta and Chen (1975) as shown in Fig. 13.2.
