Abstract
Use of radioactivation analysis for copper determination in vine-growing and in vine-products Though radioactivation analysis has been the object of works in biological research, it is not widely used in agronomy. An example of the possibilities of this new technique is given by copper determination in vine under the double aspect of trace-element copper and pesticide copper. The amounts od copper present in the different samples analysed vary from 0·1 to 1000 μg and two kinds of dosage are proposed. The first one is for trace analysis and includes a radiochemical separation of copper, the other one is applicable to amounts above 100 ppm and is a purely instrumental method without chemistry.
