Development of a method for sampling and analyzing metallic fume emitted from molten copper-base alloys is awaited since it is important in terms of controlling atmospheric pollution. An apparatus having modified heat resistant devices was developed for extracting metallic fume at elevated operating temperatures and was applied to determine the composition and quantity of metallic fume emitted during commercial melting of Cu-Pb alloys. The quantity of Pb fume from molten alloy is : C=1.59×10-2×1.03exp (5×10-3t) where, C is the quantity of Pb fume (μg/min), X is weight percent of Pb in Cu-Pb alloy and t is temperature of molten alloy (°C). The quantity of metallic fume emitted from molten alloy is in proportion to the temperature and the content of Pb in the alloy.
