本文在一维黄土土柱试验系统上，进行了弥散试验及重金属的运移规律试验，由试验得知：虽然氯离子为隋性离子，但黄土土壤对其仍具有一定吸附能力，所以利用氯离子来测定黄土区的弥散系数会存在误差，使得到的弥散度偏大。通过重金属锌在一维黄土土柱中的运移试验，确定出用以描述黄土土壤对重金属锌吸附过程的Ｆｒｅｕｎｌｉｃｈ等温模型的有关参数，同时也证实应用Ｆｒｅｕｎｌｉｃｈ等温模型来模拟黄土土壤对重金属锌吸附的合理性。并由试验看出锌在黄土体中的运移速度是相当慢的。
In this paper, one-dimensional loess soil column test system, the dispersion test and heavy metal migration rule test, the experiment shows that: although chloride ions are inert ions, but the loess soil still has some adsorption capacity, so the use of chlorine Ion to determine the dispersion coefficient of the loess area there will be errors, so that the dispersion is too large. Through the migration experiment of heavy metal zinc in one-dimensional loess soil column, the parameters of Freunlich isotherm model used to describe the adsorption process of heavy metal zinc in loess soil were determined, and the Freunlich isotherm model was also used to simulate the adsorption of heavy metal zinc The rationality. And the experiment shows that the transport speed of zinc in loess is quite slow.
