Description 341-346
Adsorption of glycine and alanine on montmorillonite
and on Ca2+- and Mg2+- exchanged montmorillonite clay
over a range of pH (4.0-9.0) and temperature (20-35oC) under possible
abiotic conditions have been investigated UV-spectrophotometrically. Adsorption
of both the amino acids was considerable on all the three adsorbents used.
Maximum adsorption was observed at 25o C and neutral pH. Ca2+-montmorillonite
exhibited relatively better adsorption as compared to Mg2+-exchanged
form or montmorillonite. The values of KL and Xm were
determined using Langmuir isotherm characteristics.
