General description
Analysis Note
Application
- A molybdenum source in the synthesis of sodium molybdate dihydrate (Na2MoO4·2H2O).
- A molybdenum source in the synthesis of nickel molybdate nanorods (NiMoO4) by co-precipitation method in the presence of nickel benzoate as a nickel source.
- A precursor in the synthesis of Mn-MoS2 (MMS). MMS is employed in the production of MMS/rGO (reduced graphene oxide) composite that exhibits the highest rhodamine B (RhB) degradation efficiency.
- A catalyst in the synthesis of PVDF (polyvinylidene fluoride) catalytic microcapsules. PVDF is a heterogeneous catalyst for the selective oxidation of benzyl alcohol to benzaldehyde.

Protocols
To measure 5′-nucleotidase activity, this procedure uses adenosine 5’-monophosphate and a color reagent to create a standard curve for determining the micromoles of phosphorus liberated.
To measure glucose-6-phosphatase activity, the Taussky-Shorr method is used. This method is a spectrophotometric stop-rate determination assay that is measured at 660 nm.
在测定5′-核苷酸酶活性时，本操作流程使用5′-单磷酸腺苷和一种显色试剂生成的标准曲线而对释放的磷的微摩尔数进行测定。
