摘　　要：通过考察不同粒径、温度、酸溶度对铅酸蓄电池正极板栅溶解性能的影响,筛选出铅酸蓄电池正极板栅的最佳溶解条件。实验结论如下:粒径越小,正极板栅溶解越快;60℃时正极板栅溶解最快,温度过高或过低均不利于板栅溶解;当硝酸浓度为1∶3时,正极板栅溶解最快,酸浓度过高或过低均不利于板栅溶解;60℃时,用1∶3的稀硝酸溶液,4 h内可将0.2 mm以下的正极板栅颗粒全部溶解,提高了正极板栅和蓄电池中镉含量测定的准确性。The effect of different particle size, temperature and acid solubility on the dissolution performance of lead-acid battery positive grid was studied to obtain the best solution condition. The experimental conclusions are as follows： the smaller the particle size is, the faster the positive grid dissolves; the positive grid dissolution is the fastest at 60℃, while higher or lower temperature is unfavorable to dissolve the grid; when the concentration of nitric acid is 1 ： 3, the positive grid dissolve fastest, while the higher or lower acid concentration is unfavorable to dissolve the grid; the positive grid particles of below 0.2 mm can all dissolve in 4 h at 60℃ by using the dilute nitric acid solution of 1 ： 3; the determination accuracy of cadmium content in positive grid and battery is improved.
