目前镀铬溶液的硫酸含量分析方法主要使用重量法和容量法两种。重量法要先沉淀过滤，再 于马福炉中灼烧，最后进行准确称量，比较复杂，消耗电能较多，所用设备较多，故不为大 多数做生产控制的化验工作者使用。而容量法以快速、简捷、所用设备少、操作方便等优点 ，为广大镀液 At present, the sulfuric acid content analysis method of chrome plating solution mainly uses two methods of gravimetric method and volumetric method. Gravimetric method should first precipitation filter, and then burning in the muffle furnace, the final accurate weighing, more complex, more energy consumption, the equipment used more, it is not for the majority of production control laboratory workers to use. The capacity method to fast, simple, less equipment, easy operation, etc., for the majority of plating solution
