Abstract

The invention relates to a preparation method of Bi<3.64>Mo<0.36>O<6.55> nanometer particles and a nanometer material made of the Bi<3.64>Mo<0.36>O<6.55> nanometer particles. The preparation method comprises the following steps: weighing proper amount of bismuth salt and dissolving the bismuth salt in certain amount of water, and under the condition of magnetic stirring, adding a nitric acid solution with certain concentration; dissolving proper amount of molybdate in the obtained solution, and adjusting the pH value with ammonia water with certain concentration; pouring the mixed solution into a crucible, and performing microwave reaction. The obtained product is sequentially washed with water and absolute ethyl alcohol for multiple times, and is dried. The bismuth salt is one type from or a mixture of bismuth chloride, bismuth nitrate and bismuth sulfate. The molybdate is one type from or a mixture of ammonium molybdate, potassium molybdate and cadmium molybdate. Through changing of solution pH value, reactant concentration and microwave frequency, the Bi<3.64>Mo<0.36>O<6.55> nanometer particles with different sizes can be obtained. Due to different electric charges on the surfaces of the Bi<3.64>Mo<0.36>O<6.55> nanometer particles, the Bi<3.64>Mo<0.36>O<6.55> nanometer particles are subjected to electrostatic interaction with different ionic pigments, so that the Bi<3.64>Mo<0.36>O<6.55> nanometer particles show high selectivity and high absorption capability in respect of absorbability.

Description

technical field

[0001] The present invention relates to a Bi 3.64 Mo 0.36 o 6.55 The preparation method of nanoparticle and its Bi 3.64 Mo 0.36 o 6.55 nanomaterials. Background technique

[0002] With the continuous deepening of the industrialization process, the global environmental pollution problem is becoming more and more serious. Textile printing and dyeing, leather, papermaking, plastics, food and other industries discharge a large amount of industrial wastewater every year, and these wastewater enters the water body without good treatment, causing serious pollution to the water body. China is a big textile country, and the textile printing and dyeing industry is also a major player in the discharge of industrial wastewater, accounting for about 35% of the entire industrial wastewater discharge. According to incomplete statistics, the discharge of printing and dyeing wastewater in my country is about 3×106 to 4×106 tons per day, so , the treatment of printing an...
