| Abstract: |
| In recent years, soil pollution has become a serious problem in China. Accurate and fast methods for the detection of heavy metals in soils can help the prevention and control of heavy metal soil pollution. Direct solid sampling technique has been widely used in the determination of various elements in agricultural soil samples because it can simplify sample preparation, shorten analysis time, and reduce the use of harmful chemical reagents. In view of this, reviews on introduction technologies of typical soil solid samples, such as electrothermal evaporation, laser ablation, plasma injection, and neutron activation, were first summarized in this article. Second, solid sampling technique was classified according to different detectors, and its principle, latest research progress both at home and abroad, and standard status were summarized. Furthermore, problems existing in soil solid sampling techniques such as sample weighing and mesh selection, calibration method, matrix interference, and elimination technology were summarized. Finally, prospects and aspects for the future development of soil solid sampling technology were summarized, which include automation degree, field application, accuracy improvement, and cost saving. |
