对钒催化剂中钒和钾含量的测定是确定它能否继续使用的主要依据。用部颁标准分析方法测定时，分解样品需要采用象氢氟酸、高氯酸等腐蚀性极强的药品及白金坩埚等贵重仪器，给一般工厂化验室进行测定带来很多的不便。对此，我们改进了分解样品的方法并简化和改进了分析方法... Determination of vanadium and potassium content of vanadium catalyst is the main basis to determine whether it can continue to use. Determine with the ministry standard analytical method, the decomposition of samples need to use such as hydrofluoric acid, perchloric acid and other highly corrosive chemicals and platinum crucible and other valuable equipment to the general factory laboratory for a lot of inconvenience. In this regard, we have improved the method of disassembling the sample and simplified and improved the analytical method ...
