摘要
对11种煅品、生品自然铜中砷含量进行了测定和比较。结果表明,砷含量生品比煅品高约10倍,说明自然铜经炮制后可除去或降低其毒性。
Determination and comparison of arsenic contents in 11 samples of calcinated and pig native copper have been conducted. The results reveal that arsenic contents in pig native copper are about 10 times of those in the calcinated samples. Therefore the toxic effect of native copper can be eliminated or reduced after it is calcinated.
