Technology Description

The technology is a new dye-removal material. It consists of a composite particle having a "core-shell" structure with the core made up of a magnetic ceramic particle and the shell made up of a dye-adsorbing material.

This alternative dye-removal material can remove the textile-dyes from an aqueous solution (textile-effluent) via surface-adsorption mechanism under the dark condition (that is, without any exposure to the sunlight or ultraviolet-radiation) in minimum amount of time. So, it saves time and energy compared with the existing dye-removal technology.

Applications

• Dye-Manufacturing Industries,
  
• Effluent Treatment Plants,
  
• Water Purification Systems
  

Benefits

• The new dye-removal technology works on the surface-adsorption mechanism, which is an energy-independent process (that is, it does not require any exposure to the sunlight or ultraviolet-radiation).
  
• It removes the textile-dye from an aqueous solution in less than 30 min under the given test-conditions; while, the conventional materials take few hours for the complete dye-removal under the same conditions.
  
• No costly chemicals are required for the material separation after the dye-adsorption process.
  
• External magnetic field can be utilized for the material separation which is not possible with the present dye-removing materials.
