Chitosan polymer removes heavy metals from aquaculture water bodies

Chitosan is an effective material for removing heavy metals from aquaculture water bodies. Chitosan is a natural polymer compound with good adsorption and ion exchange properties, which can adsorb organic matter, heavy metal ions, and ammonia nitrogen in water, effectively purifying water bodies. In addition, chitosan also has unique properties such as biocompatibility, biodegradability, and cell affinity, making it less polluting to the environment. When chitosan is dissolved in an acidic medium, its amine matrix undergoes protonation, exhibiting cationic properties and bridging and trapping effects of polymer flocculants. It can capture organic matter and heavy metal ions in water, while also inhibiting the reproduction and growth of microorganisms in water, and has a certain bactericidal effect. These characteristics make chitosan suitable as an adsorbent, flocculant, chelating agent, etc. for use in water treatment

Specifically in the field of aquaculture, the applications of chitosan include but are not limited to the following:

Purification of water quality: Chitosan can adsorb heavy metal ions in water, such as lead, cadmium, copper, etc., effectively reducing the concentration of these heavy metals in aquaculture water, thereby reducing the toxic effects on aquaculture organisms.

Improving aquaculture water: Through the adsorption of chitosan, harmful substances in water can be removed, improving the quality of aquaculture water and providing a healthier growth environment for aquaculture organisms.

Enhancing the immunity of aquaculture organisms: The use of chitosan also helps to enhance the immunity of aquaculture organisms, improve their adaptability to the environment and disease resistance.

In summary, chitosan, through its unique physical and chemical properties, has shown significant effects in removing heavy metals from aquaculture water bodies. It not only helps improve water quality but also promotes the healthy growth of aquaculture organisms.

Chitosan and HCL are two good choice in aquaculture water treatment on heavy metal.
