现在,国家每年要消耗大量的铅等金属作蓄电池,因此提高其寿命,改善其性能对国民经济将产生实际效益。影响蓄电池寿命的主要因素是板栅合金的成份及其制造工艺。经过反复试验,我们找到了如本文所分析的这种板栅合金成份的光谱定量分析方法。实验标样的配制: 1.基体PbSO_4的配制:取光谱纯Pb25克放在瓷坩埚中,用高纯稀硝酸(1:3)将表面洗净,立即用蒸馏水冲洗数次。再加人高纯稀硝酸(1:3)在电炉上缓缓加热至铅完
Nowadays, the state consumes a large amount of lead and other metals as a battery every year, so improving its life and improving its performance will have tangible benefits to the national economy. The main factor that affects battery life is the composition of grid alloy and its manufacturing process. After repeated experiments, we have found the spectral quantitative analysis method of this grid alloy composition as analyzed in this paper. Preparation of experimental standards: 1. The preparation of matrix PbSO_4: Take pure Pb25 grams of the spectrum in a porcelain crucible, wash the surface with high purity dilute nitric acid (1: 3) and rinse immediately with distilled water several times. Coupled with high purity dilute nitric acid (1: 3) slowly heated to the lead on the electric furnace
