T/GDNB 46-2021 Extraction of soil heavy metal bioavailability in paddy soil The diffusive gradients in thin film-inductively coupled plasma optical emission spectrometry (English Version)
This document specifies the principles, reagents, instruments and equipment, sample preparation, and sample preparation for the quantitative determination of inductively coupled plasma emission spectroscopy using diffusive gradient inthin-films (DGT) method to extract the available state of cadmium in rice field soil. Extraction, determination, and result calculation. This document is applicable to the determination of the available forms of cadmium in rice field soil. The extraction and determination of other heavy metals such as lead (Pb), copper (Cu), nickel (Ni), zinc (Zn) and other available forms in rice field soil can be performed with reference to this standard.
