Uptake characteristics of chemical pollutants by means of Reed and its application to water remediation

本研究旨在探讨芦苇对肥料或土壤中溶解的化学污染物的吸收特性，并将其应用于水体修复。通过一系列的铜溶液柱实验，测定了根周对水中铜和KNO_3的吸收特性，并测定了木炭对铜的吸附性能。清水的污染物数据由Reed通过田间试验收集。本研究的主要结果得出以下结论。(1)利用Freundlich模型估算了木炭对铜和KNO_3的吸附量，明确了在回收木材中，木炭对铜和KNO_3的最大吸附量为6%。(2)芦苇的吸收对铜污染的修复有显著的影响。(3)证实了污染水中ch.1与芦苇中ch.2的电导率电压差是由于清水现场站芦苇的吸收能力所致

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
