The aim of this study is to examine the uptake characteristics of chemical contaminants dissolved from the fertilizers or soils by means of Reed, and more to apply the method to the water remediation.The uptake properties of copper and KNO_3 in water were measured around roots and the copper adsorption test of charcoal were determined by a series of copper solution column experiment.The data of contaminants in Shimizu was collected through the field experiment by Reed.The main results of the study lead to the following conclusions.(1)The amount of copper and KNO_3 adsorption around charcoal has been estimated by Freundlich model, and it has been clarified that the maximum value is 6% in charcoal which is wade of recycle woods in order to remediate the contaminated water(2)It has been demonstrated that the uptake of Reed have significant effects on the remediation of copper contamination.(3)It has confirmed that the voltage difference of electrical conductivity between ch.1 in contaminated water and ch.2 in Reed contributes due to the uptake ability of Reed in the Shimizu field station

本研究的目的是研究芦苇对化肥或土壤中溶解的化学污染物的吸收特性，研究了铜离子和硝酸钾离子在水体中的吸附特性，并对该方法在水体修复中的应用前景进行了展望。采用铜溶液柱法测定了清水县清水县3种污染物的含量，并对清水县3种污染物的含量进行了测定研究的主要结果得出以下结论。（1）用Freundlich模型估算了铜和KNO_3在活性炭上的吸附量，明确了再生木吸附铜和KNO_3的最大吸附量为6%。（2）芦苇吸附铜和KNO_3对铜污染有明显的修复作用。(3)It证实了清水野外站芦苇的吸收能力是由于受污染水体中的ch.1和芦苇中的ch.2之间的电导率的电压差造成的
