Preparation of medicament and measures to improve its efficacy

The suitable dosage and effect of the same medicament are different with different preparation methods. The choice of preparation method mainly depends on the properties, adding methods and functions of the medicament.

Most water-soluble chemicals are prepared into aqueous solutions, such as xanthate, copper sulfate, zinc sulfate, potassium dichromate, etc., which are usually prepared into 5% - 10% aqueous solution.

For some insoluble chemicals, special methods should be used for preparation. For example, after grinding the lime to 10-1001 m, it is mixed with water at room temperature to prepare lime milk; the fatty acid collector is saponified and used; the fatty acid, amine collector and white drug are dissolved in some specific solvents to make the liquid medicine; for oleic acid, kerosene, terpineol oil and diesel oil, strong mechanical stirring or ultrasonic treatment is used Emulsifying or emulsifying agents can be used after emulsification. A special spray device can also be used to make the agents atomized in the air and use (aerosol method).
