铅青铜中的铅一般都用铬酸铅重量法或容量法测定。今年一月份技术简报曾介绍铅的快速法(直接用铬酸铅沉淀,最后以碘量法完成),但试验周期较长,需要三小时才能得出结
Lead in lead bronze is generally measured by chromate weight or volumetric method. The technical briefing in January this year introduced the rapid method of lead (direct precipitation with lead chromate and finally iodization), but the test period is longer and takes three hours to reach the conclusion
