磷青铜是一种常见的合金材料。其锡、磷、铜的含量,一般是单独称样,分别测定的,手续比较麻烦。我厂试验成功一种比较简单的方法,即制成一个母液,分取出来各个测定的方法。该方法的主要优点是:节约标样、试剂、人力和时间。如:用原方法时,测定锡含量需两份0.5克(或1.0克)标样,测定铜含量需两份0.1克(或0.5克)标样,测定磷含量需用0.1克标样,合计需用标样(以最低量计算)1.3克,用本方法时;仅需一次称取标样0.4克,节约标样70％,称样时间也可减少80％。另外,现用络合滴
Phosphor bronze is a common alloy material. The tin, phosphorus, copper content, usually individually weighed, were measured, the procedure is too much trouble. I plant a successful test a relatively simple method, that is made of a mother liquor, points out the method of determination. The main advantages of this method are: saving standards, reagents, manpower and time. Such as: the original method, the determination of tin content required two 0.5 g (or 1.0 g) standard sample, the determination of copper content required two 0.1 g (or 0.5 g) standard, the determination of phosphorus content required 0.1 g standard sample, total Need to use the standard (minimum amount) 1.3 grams, with this method; only need to weigh the standard sample 0.4 grams, saving 70% of the standard, said the sample time can be reduced by 80%. In addition, now with complex drops
