ヨシ水路による河北潟水の浄化について検討を行った。有機態炭素, 窒素, リンそれぞれについて懸濁態と溶存態に分画し, 溶存成分はさらにゲルクロマトグラフィーを用いて分子量別に分画して浄化の効果を調べた。全窒素, 全リン, BOD, CODについては, 溶存態よりも懸濁態の方がヨシ水路によってより効率的に除去さることが明らかとなった。ゲルクロマトグラフィーによって分けられた3つの溶存有機物画分のうち, ヨシ水路の通過後, 最も分子量の小さい画分3のピークが減少したのに対して分子量最大の画分1のピークは増加した。ヨシ水路を用いた河北潟水の浄化後, 親水性成分の割合が増大した。これは疎水性成分の除去される割合が親水性成分よりも高いことを示唆する。The effect of reed bed system on the quality of Kahokugata lagoonal water was studied. The effects on water quality were examined by fractionation of dissolved organic carbon, nitrogen, and phosphorus using gel-chromatography. The suspended components of total nitrogen, total phosphorous, BOD, and COD were removed using reed bed system more efficiently than the soluble components of total nitrogen, total phosphorous, BOD, and COD. Based on UV220, UV260, TOC, T-N, and T-P three major fractions were identified by gel-chromatography of Kahokugata lagoonal water. Among them, the 3rd fraction (the lowest molecular weight) decreased after passing through the reed bed, while the 1st one with the highest molecular weight increased. The relative ratio of hydrophilic component increased after the purification of Kahokugata lagoonal water using reed bed system; this suggests that the removal ratio of hydrophobic component was higher than that of hydrophilic component
