M. Wood2; M.

Journal of Zhejiang Agricultural University, 1997,23 (1): 46 ~ 48 Abstract In soil column leaching experiments, bromide ion is usually used as a conventional marker for the volume of the pore volume. In this study, the saturated leaching test of soil column filled with soil in Sonning soil system in England was carried out by bromine labeling method. The results show that the leaching of bromide ions is faster than expected with respect to the tritiated peak leached with standard tritiated water. Therefore, it is speculated that bromide ion should not be used as a tracer to estimate the pore volume of water because anion exclusion may occur in the soil of the Sonning soil system. Soil adsorption of bromide ions also partially confirmed the above results
