Abstract
Analysis of lead and cadmium fume, particularly the method to capture their fume, was studied. The experiment was performed by a combination of an impinger method that is used for water, nitric acid, and sulfuric acid, and a filter sampler method. Result: the impinger method couldn't capture the fumes completely, but the filter caught than 99.5% of them. Use of 1 or 2 pieces of glass fiber filter, or 2 or 3 pieces of No. 6 filter paper was effective. From an observation of the fumes by an electronmicroscope, it was known that these fume perticles join each other as a chain than, they are caught by filters easily. Their analysis was made by atomic absorption spectrophotometry.
