Application of Ammonium Heptamolybdate
Used in fields such as powder metallurgy, chemical industry, petrochemicals, agriculture, etc
In the field of agriculture, ammonium molybdate is used as a trace element fertilizer for plant growth. Molybdenum is one of the essential trace elements for plant growth, participating in photosynthesis and nitrogen metabolism in plants. The molybdenum element in ammonium molybdate can promote plant growth and development, improve crop yield and quality. Especially when planting leguminous crops, the application of ammonium molybdate can promote the nitrogen fixation effect of rhizobia, increase the nitrogen content in the soil, and improve the stress resistance of crops.
In the field of materials science, ammonium heptamolybdate is also used as a raw material for preparing molybdenum based composite materials. By mixing ammonium molybdate with other metal salts, molybdenum based composite materials with excellent properties can be prepared. These composite materials have the characteristics of high strength, high hardness, high temperature resistance, and oxidation resistance, and are widely used in aerospace, energy, chemical and other fields.
In addition, ammonium molybdate also plays an important role in the pigment and dye industries. Due to its unique structure and properties, ammonium molybdate can be used as a raw material or additive for dyes, endowing them with specific colors and properties. This dye can be used for dyeing and printing textiles, providing the textile industry with rich color choices and good dyeing effects.
In the field of environmental governance, ammonium molybdate also demonstrates its unique advantages. Due to its good redox performance, ammonium heptamolybdate can be used to treat pollutants such as sulfur and nitrogen. By reacting with these pollutants, ammonium heptamolybdate can convert them into harmless or low toxicity substances, thereby achieving the goal of purifying the environment. For example, when dealing with acidic mine drainage, ammonium molybdate can serve as an effective neutralizing agent, regulating pH values and reducing the harm of acidic water.

FAQs of Ammonium Heptamolybdate
Q:What are the main uses of ammonium heptamolybdate?
A:Ammonium heptamolybdate is a precursor for many industrial catalysts, especially in petroleum refining and chemical synthesis for desulphurisation, denitrogenation and isomerisation reactions. Molybdenum is an essential trace element for plant growth. Ammonium heptamolybdate can be used as a trace element fertiliser to replenish molybdenum in the soil and promote plant growth. Ammonium heptamolybdate can be used to prepare molybdenum-based coatings and pigments to improve the corrosion and weather resistance of materials. Ammonium heptamolybdate is used as a standard solution for molybdenum in chemical analyses to determine the molybdenum content of samples. Ammonium heptamolybdate also has applications in medicine and biotechnology, e.g. in the preparation of certain drugs and biological reagents.
Q:How to prepare ammonium heptamolybdate?
A:Prepare a sodium molybdate solution by dissolving sodium molybdate in water. Concentrated ammonia was slowly added to the sodium molybdate solution with stirring. A white precipitate is produced during the reaction and after continuing stirring for some time, the precipitate is separated by filtration. The precipitate is washed several times with distilled water and then dried in a drying oven to obtain heptamolybdate crystals.
Q:What is the safety and environmental impact of heptamolybdate?
A:Ammonium heptamolybdate itself has low toxicity, but excessive intake of elemental molybdenum may lead to molybdenum toxicity, manifested by gastrointestinal discomfort, headaches and anaemia. Therefore, prolonged exposure or ingestion of large quantities should be avoided. Ammonium heptamolybdate is slightly irritating to the skin and eyes. Appropriate protective equipment, such as gloves and goggles, should be worn during handling. The accumulation of molybdenum in the environment may cause effects on aquatic organisms. Therefore, direct discharge of wastewater containing ammonium heptamolybdate into the environment should be avoided and requires appropriate treatment before discharge. Ammonium heptamolybdate should be stored in a dry, ventilated place away from sources of ignition and strong oxidising agents. When transporting it, the relevant regulations on dangerous chemicals should be observed to ensure safety.
Q:How soluble is ammonium heptamolybdate in water?
A:Ammonium heptamolybdate has a high solubility in water, depending on the temperature. Generally, the solubility of heptammonium molybdate at room temperature is about 100 g/L. As the temperature increases, the solubility increases. For example, at 20°C the solubility of ammonium heptamolybdate is about 100 g/L, while at 100°C the solubility can reach about 200 g/L. This high solubility makes ammonium heptamolybdate easy to handle and apply in aqueous solutions.
