Colorless monoclinic or prismatic crystals or white powder, oxalic acid produced by oxidation has no odor, while oxalic acid produced by synthesis has an odor. Oxalic acid can be used as a cleaning agent because it can bind with various metal ions and minerals, effectively removing scale and lime deposits. In the dye industry, oxalic acid can combine with certain chemicals to form dyes and act as a stabilizer for the dyes. In addition, oxalic acid is also used in various fields such as leather processing, chemical reagent preparation, and photovoltaic industry.
The characteristics of ammonia nitrogen removal agents for river treatment are chlorine free. Unlike the commonly used ammonia nitrogen removal agents in the market, they are mainly suitable for treating rivers, with obvious treatment effects. After adding the agents, they can remove ammonia nitrogen, color, odor, etc. from water; It is evident that the river water is clear and the ammonia nitrogen in the water has significantly decreased; It can be applied to various stages of biochemical treatment and has flocculation and sedimentation effects, which can be used as a substitute for flocculation agents. This is mainly used in wastewater with ammonia nitrogen<50ppm.

The advantages of oxalic acid are mainly reflected in its various uses and effects, with the following main advantages:
1. Industrial applications
Oxalic acid has a wide range of industrial applications:
Cleaning and stain removal: Oxalic acid can bind with metal ions and is commonly used to remove rust and scale. It is the main component of some cleaning agents. It can also be used for bleaching or fixing dyes to enhance the dyeing effect.
Chemical synthesis: Oxalic acid is used as an intermediate in some chemical production to synthesize other compounds. Its salts, such as potassium oxalate and sodium oxalate, are also used in various chemical processes.
Environmental application: Oxalic acid can treat heavy metal pollution by combining with heavy metal ions to form soluble oxalates, which help to remove pollution. In addition, it is also used to treat wastewater and exhaust gas, reducing the emission of pollutants.
2. Medical applications
In the field of medicine, oxalic acid also has various applications:
Pharmaceutical manufacturing: Oxalic acid is used to manufacture drugs such as streptomycin, oxytetracycline, tetracycline, streptomycin, borneol, vitamin B12, phenobarbital, etc.
Laboratory applications: Oxalic acid is used as a reducing agent and a raw material for the preparation of other compounds in the laboratory, participating in many chemical reactions.
