| Abstract: | In this paper, the determination of trace elements including copper, manganese,cobalt, nikel and chromium in lead metasilicate by atomic absorption spectroscopyhas been investigated. The influence of interfering elements and the acidity of thesolvent medium on the determination was examed. The optimum working conditionsof the determination were found using orthogonal experimental design techique met-hod of analysis. On the basis of the elimination of various interfering factors ananalytic method of the succesive determination of five elements by one single sam-pie digestion was worked out. |
