Laboratory Chemical Reagent Aluminum Sulfate is a commonly used inorganic chemical reagent, widely used in the field of water treatment, especially in water purification experiments, its effect has attracted much attention. As a coagulant, Laboratory Chemical Reagent Aluminum Sulfate can effectively remove suspended matter, turbidity and some soluble organic matter in water, thereby improving water quality.
1. Chemical properties of Laboratory Chemical Reagent Aluminum Sulfate
Laboratory Chemical Reagent Aluminum Sulfate will undergo hydrolysis in water. During the water treatment process, aluminum hydroxide precipitation can absorb suspended matter and impurities in the water to form floccules with larger particles, which is convenient for subsequent precipitation and filtration operations.
2. Water purification process
In water purification experiments, when using Laboratory Chemical Reagent Aluminum Sulfate, the following steps are usually followed:
Adding reagents: According to the concentration and properties of suspended matter in the water, scientifically calculate the required amount of Laboratory Chemical Reagent Aluminum Sulfate and evenly add it to the water to be treated.
Stirring reaction: After adding Laboratory Chemical Reagent Aluminum Sulfate, stir it thoroughly to make it fully contact with impurities in the water, promote hydrolysis reaction and flocculation process.
Sedimentation and separation: After mixing evenly, let it stand for a period of time to allow the formed floccules to settle to the bottom of the water, and then discharge the clear liquid or further treat it.
3. Effect evaluation
The superior effect of Laboratory Chemical Reagent Aluminum Sulfate in water purification experiments is mainly reflected in the following aspects:
Removing suspended matter: Laboratory Chemical Reagent Aluminum Sulfate can effectively remove suspended matter in water and significantly reduce the turbidity of the water body.
Removal of heavy metals and organic matter in water: Under certain conditions, Laboratory Chemical Reagent Aluminum Sulfate can also help remove some heavy metal ions and organic pollutants in water, further improving water quality.
Improve precipitation efficiency: By adding Laboratory Chemical Reagent Aluminum Sulfate, the generated aluminum hydroxide flocs can effectively increase the precipitation rate and shorten the purification time.
4. Precautions
Although Laboratory Chemical Reagent Aluminum Sulfate is effective in water treatment, you still need to pay attention to its dosage when using it. Excessive use may cause aluminum ions to exceed the standard in water, thereby affecting the water ecology. In addition, sufficient stirring and appropriate precipitation time should be ensured during the experiment to achieve the best purification effect.
In general, Laboratory Chemical Reagent Aluminum Sulfate is a chemical reagent widely used in water purification, and its effectiveness cannot be underestimated. Through appropriate use methods, Laboratory Chemical Reagent Aluminum Sulfate can significantly improve water quality, reduce pollutants in water, and provide guarantees for the safety of drinking water and the sustainable use of water bodies.
