Determination of the Cation-Exchange Capacity of Muscovite Mica

Journal of Colloid and Interface Science, 2000
High cation-exchange capacity (CEC) muscovite mica with a homoionic surface was prepared by replacing the Li(+) surface ions of partially delaminated Li-mica with K(+). The CEC of this K-mica was determined by exchanging its surface cations with Cs(+), NH(+)(4), methylene blue (MB(+)), and copper triethylenetetramine [Cu(trien)(2+)].

Cation exchange capacity measurements

Communications in Soil Science and Plant Analysis, 1982
Abstract Soil cation exchange capacity (CEC) measurements are important criteria for soil fertility management, vaste disposal on soils, and soil taxonomy. The objective of this research was to compare CEC values for arable Ultisols from the humid region of the United States as determined by procedures varying widely in their chemical conditions during

The Lower Cation Exchange Capacity Limit of Montmorillonite

Journal of Colloid and Interface Science, 1999
Wyoming montmorillonite (Volclay) with different charges were produced by Li-incorporation and the interlayer cations were replaced by tetramethyl ammonium. Their XRD pattern showed a regular sequence of expanded and collapsed interlayers. The regularly interstratified structure corresponds to a regularity of Reichweite R = 1.

Determination of cation exchange capacity of ryegrass roots by summing exchangeable cations

Plant and Soil, 1989
Cations were desorbed from root exchange sites of ryegrass (Lolium multiflorum Lam. cvs. Gulf, Marshall, Urbana, and Wilo) using BaCl2, BaCl2-triethanolamine, NH4OAc, and KCl. Results were analysed using multivariate analysis of variance. Ba2+-containing desorbents displaced more Ca2+ while monovalent desorbents displaced more exchangeable monovalent ...

Cation‐Exchange Capacity and Exchangeable Cations in Piedmont Soils of North Carolina

Soil Science Society of America Journal, 1959
Abstract Soils of the North Carolina Piedmont were analyzed for permanent‐ and pH‐dependent charge components of cation‐exchange capacity. Permanent charge was taken as the summation of exchangeable metal cations, including Al displaced upon leaching with a neutral salt solution; pH dependent charge was regarded ...

Cation exchange capacity methodology I: An efficient model for the detection of incorrect cation exchange capacity and exchangeable cation results

Applied Clay Science, 2006
Abstract In this study a model is proposed enabling the detection of incorrect cation exchange capacity (CEC) and exchangeable cation values. Numerous CEC and exchangeable cation analyses of clayey sediments, soils and bentonites were performed using triethanolamine-buffered barium chloride, ammonium acetate, silver thiourea and other exchange ...
