铬酸清洁液的氧化去污能力取决于铬酸酐的多寡和硫酸的浓度.即络酸酐生成的越多、硫酸的浓度越高,其氧化去污能力越强.文献所载之配制方法,由于必须将重铬酸钾溶解于水而使硫酸的浓度降低,并且在操作中由于产生高温而使硫酸溅出容器,甚至使容器炸裂。为此,作者做了如下实验,配制的方法及处方见附表.
Oxidative decontamination capacity of chromic acid cleaning solution depends on the amount of chromic anhydride and the concentration of sulfuric acid that the more the acid anhydride generated, the higher the concentration of sulfuric acid, the stronger its ability to oxidative decontamination The preparation method described in the literature, as a result of The potassium dichromate must be dissolved in water to reduce the concentration of sulfuric acid, and sulfuric acid is spilled out of the container due to the high temperature generated during the operation, and even the container is burst. To this end, the author did the following experiment, preparation methods and prescriptions see the attached table.
