Atrazine Degradation, Sorption and Bioconcentration in Water Systems [PDF]
, 1982 The herbicide atrazine is used extensively to control broadleaf and grass weeds in such crops as sorghum and corn. A small portion of the atrazine may be lost from the area of application by surface runoff and could enter a stream or lake.

Water sorption behavior of polysaccharides.
KOBUNSHI RONBUNSHU, 1988 デンプンをもととし, そのカルボキシメチル化及びアクリル酸とのグラフト共重合生成物を作製し, それらの吸湿, 吸水挙動について検討した. デシケーター法による吸湿性の測定結果から, いずれの試料も初期の増加率が著しく, ほぼ15-20日間で平衡となった. 平衡時における各々の吸湿曲線はシグモイド型を示した. さらに, 相対湿度40%までの条件下の各試料の値には B. E. T. 理論が成り立った. 1グルコシド繰返し単位当たりの単分子吸着量はG (S-AA) が7.37分子, G (CMS-AA) が4.69分子, CMSが0.73分子であった.
