An Ultraviolet Spectroscopic Method for Monitoring Surface Acidity of Clay Minerals under Varying Water Content
Monitoring Surface Clay Minerals Varying Water Content
2012/2/15
The ability of a clay mineral surface to function as an acid is not represented by bulk pH measurements. A method using u.v. analysis and organic indicators has been developed to monitor surface acidi...
Relation of Potassium Exchange and Fixation to Degree of Weathering and Organic Matter Content in Micaceous Clays of Podzol Soils
Potassium Exchange Degree Weathering Organic Matter Content Micaceous Clays
2012/2/20
The rates of K exchange of untreated and peroxide-treated micaceous clays from five Podzol soils of increasing degrees of weathering were determined using sodium tetraphenyl boron. In addition, the am...
