原子吸收光谱法测定铅蓄电池板栅中锡、钙和铝

Determination of Sn,Ca and Al in Lead Electrode Plane of Lead Storage Battery by AAS

通过先加酒石酸、硝酸溶解样品,用氧化镧、EDTA联合掩蔽铝来测定钙,盐酸沉淀铅后测锡、铝的试验,采用火焰原子吸收光谱法测定锡、钙和铝。

The sample was dissolved by nitric acid and tartaric acid,and determined by AAS with lanthanide oxide and EDTA masking AI for determination of Ca, with HCl precipitating Pb for determination of Sn and Al.
