On the basis of this, from the comparative experiments of several halogenides, we have found that the addition of sodium bromate has the highest sensitivity effect in the determination of tin.
在此基础上,我们对几种卤化物作了比较试验,发现加入溴化钠对测定锡的灵敏度最高。
The existing bath analyzing methods are compared, as a result a quick and continous method for determining sodium hypophosphite and stannum(II) ion in electroless tin bath is determined.
并对现有的镀液分析方法进行了比较,确定了快速连续测定化学镀锡液中亚锡离子和次磷酸钠的方法。
The sodium stannate from slag containing tin is prepared directly by the process including alkali fusion, leaching, purification, concentration and crystallization.
以含锡渣为原料,采用碱熔—浸出—除杂—浓缩结晶工艺直接制取了锡酸钠产品。
