title: Effect of some anions on the mobility of amino acids in soils by thin layer chromatography.
abstract: The mobility rate of some cyclic and aliphatic amino acids in terms of Rf values by using soil-thin layer chromatography shows the following order: glutamic acid > histidine > valine > leucine > serine > alanine. After conducting the studies to determine the effect of some anions, viz. MoO4(2-), B4O7(2-), C2O4(2-),CO3(2-), HCO3- and H2PO4- on the mobility of those amino acids, the mobility of the amino acids was found to increase with the increasing concentration of these anions up to a certain limit and thereafter the mobility rate declined except in case of glutamic acid which shows a fall in its movement throughout the entire range of their application in all cases. The results have been explained on the basis of a reaction mechanism involved in the interaction of these anionic species with soil colloids and amino acids in soil solution.
