Application

Ammonium molybdate can be used to determine phosphate, arsenate, lead, alkaloid; The phosphorus content of soil and plant can be determined by molybdenum blue method. It can also be used to determine the activity of inorganic phosphorus and alkaline phosphatase in serum. Determination of silicon and phosphorus in steel; Reagent for ceramic glaze and layer analysis. It can also be used as a catalyst in the petroleum industry and for molybdenum production in the metallurgical industry. Agricultural use: Molybdenum is an indispensable element for plant growth. Ammonium molybdate is an important trace element fertilizer used in agriculture. With the development of agricultural production, molybdenum fertilizer is more and more recognized by people, and has been widely used in agricultural production, with obvious effect of increasing production. The germination rate of seeds can be increased by mixing and soaking seeds with ammonium molybdate. Topdressing outside the root: topdressing outside the root with ammonium molybdate can promote the growth of crops.
