铜合金中低含量铅的测定,一般采用有机溶剂将铅从大量铜中分离出来,然后进行比色法测定。分析过程繁杂,时间冗长,且劳动条件差。光谱法和原子吸收光谱法操作虽然简单、快速,但是受到设备的限制,至今尚未普及。一般极谱法测定铜合金中低含量铅,都采用富集分离等手续,时间较为冗长, Determination of low levels of lead in copper alloys, the general use of organic solvents will be separated from a large number of copper lead, and then colorimetric determination. Analysis process is complicated, time-consuming, and poor working conditions. Spectral and atomic absorption spectroscopy operations, though simple and fast, are limited by equipment and have not yet become widespread. General Determination of lead in copper alloy by the general polarographic method, are used procedures such as enrichment and separation, the time is more lengthy,
