INTENSITY OF REMOVAL OF CATIONS FROM COTTON, CORN, AND SOY BEAN TISSUE BY FRACTIONAL ELECTRODIALYSIS

Abstract
To determine the intensity of removal of cations, fresh samples of cotton, com and soybean tissue were electrodialyzed in a Loddesol Electro-dialysis apparatus and analyses made of the diffusate collected at successive intervals for a total of 29 to 32 hours. A differential was found in the intensity of removal of various metals from plant tissue the strongest ions are removed the most readily, and large proportions of the strong K and Na ions were found in the first fractions of the diffusate. The percentages of the total amts. of K, Na, Ca and Mg extracted from cotton tissue during the 1st hr. period were 91.40, 49.57, 31.1 and 1.60%, respectively. During the 3-5 hr. extraction period, the above quantitative relations were reversed, the percentages of the total amounts removed being 0.5, 5.18, 11.9, and 60.2% respectively.
