pH has been determined in some lakes by using an in situ technique.
pH has also been measured in the usual way in the field and in the laboratory.
These measurements, together with the determination...

Acidification has caused the loss or reduction of numerous Atlantic salmon (Salmo salar L.) populations on both sides of the North Atlantic. Acid deposition peaked in the 1980's and resulted in both c...
氢氧化铁胶体/水界面作用与地表水中稀土元素的分异—— pH控制机理的实验研究
稀土元素 吸附 四重效应 水/粒界面作用

2009/2/25
实验研究了pH对REE水/粒界面配分行为的影响: 氢氧化铁胶体对REE的作用在胶体形成开始以吸附为主, 然后是解吸, 最后是吸附/解吸趋向平衡; 轻稀土元素(LREE)和重稀土元素(HREE)的吸附率不同, 后者大于前者. 随pH增加, LREE和HREE在氢氧化铁胶体/水之间产生分异, 其配分系数比值(DLREE/DHREE)降低; DREE的分布模式呈现Y的异常(DY/DHo<1)并在低pH条...
