Total concentration of potassium, calcium and chlorine was determined in the presence of each other and irrespective of the nature of their compounds, in the leaves of Urticae dioico L. and Spinacia oleracea L. (spinach) plants by EDXRF. The enhancement of potassium K X-rays due to calcium K X-rays and enhancement of chlorine K X-rays due to potassium and calcium K X-rays present in the samples were avoided by selective secondary excitation method of the samples. Our, results were compared with other experimental results. (C) 2005 Elsevier Ltd. All rights reserved.
