• Citric acid also called citric acid, is a metabolite of plants and animals that exists in nature. It is the most organic acid obtained from citrus fruits. Acidic, ph-modifying, antioxidant, detergent, astringent, etc. Organic acid, widely used as a chemical, is important in biochemistry as an intermediate step in the citric acid cycle in metabolism and as an environmentally friendly cleaning agent.
• Acetic acid or acetic acid is one of the representative carboxylic acids, and the molecular formula is CH 3 COOH. It is also known as acetic acid because it contains about 3 to 5% of the main ingredient of vinegar and gives the sour taste of vinegar. Pure is known as glacial acetic acid because it has a high freezing point and easily becomes a solid in winter.

• NaClO sodium hypochlorite
• sodium hypochlorite (NaClO) generates oxygen by reaction in water and uses cyanogen to make cyanic acid present in the wastewater. After that, the cyanic acid is decomposed again into nitrogen and carbon dioxide to be harmless. The lower the pH, the stronger the bactericidal power, and the lower the bactericidal power by protein, sugar, amino acid and the like. The sterilizing power is best adjusted to pH8-9 after dilution to 100ppm concentration.
• Sodium hypochlorite is a pale greenish yellow or colorless liquid, smells of chlorine, and when stored for a long time, it is decomposed and converted into chlorine gas, which loses its effect as a disinfectant.
• Such sodium hypochlorite is used as a disinfectant for removing rot or pathogens of food and is used as a disinfectant disinfectant, bleach and oxidant. This substance breaks down and releases oxygen. It dissolves well in water and decomposes as a disinfectant when stored for a long time because aqueous solution decomposes during storage to generate chlorine gas.
