About this Research Topic
Dyes strongly affect the photosynthetic function of plants and the aquatic life due to its low light penetration and oxygen consumption. Dyes are very stable and non-bio-degradable compounds. Hydrogels have high degrees of swelling, environmental sensitivity, and high permeability. The response of hydrogels to environmental parameters is an active area for researchers especially at pH solutions. The pH sensitive amphiphilic hydrogels, containing both cationic and anionic units, introduce an important major class of polymeric materials. Due to its responsiveness to different environmental stimuli such as pH influence, the amphiphilic hydrogel has been widely used for water treatments.
Considering this critical point of water scarcity, new and effective methods must be sought to make the most of industrial wastewater, especially contaminated with dyes. Therefore, this wastewater must be treated using of polymers membrane and hydrogels that act as an adsorbent for desalination and selectively remove pollutants from different water sources. Recent advances in the design and synthesis of hydrogels for a wide range of applications have been made by introducing other compatible materials with them. The researchers should have the ability to develop water treatment techniques using natural or environmentally friendly polymers, in addition to using inexpensive and environmentally friendly preparation methods as well. They should also ensure the ability of new hydrogels and membranes to treat water and to be easily removed. This approach aids in the ability to remove dissolved dyes based on their chemical identity. The interesting thing about self-assembling polymer membranes is that you can engineer the nanostructure and wall pores of the membrane by designing the polymer molecules. This has the potential to unlock a variety of new separation mechanisms that can isolate species based on chemical identity.
The Research Topic will cover the pH-sensitive hydrogel for dye removal systems in all aspects including the following topics but not limited to:
• Eco-friendly materials for pH-sensitive hydrogels.
• The swelling behaviour of hydrogel as a function of pH at room temperature.
• Physical and analytical testing of pH-sensitive hydrogel.
• UV-Vis spectrum analysis to evaluate the dye removal process.
• Impact of pH on dye removal.
• Adsorption capacity (mg/g) at wide range of pHs
• Determine the high removal efficiency of dye by hydrogel and their reusability
