First Claim
Patent Images
1. A one step process for the removal of organic dye and/or organic pollutants from solution using titanium peroxide gel, the process comprising:
- a) adding titanium peroxide gel into the solution in ratio ranging between 1;
5 to 1;
20 volume/volume of gel/dye solution;
b) shaking the mixture as obtained in step (a) vigorously at temperature ranging between 25-35°
C.;
c) allowing the mixture as obtained in step (b) to stand for 5 to 25 minutes to obtain dye or organic pollutant adsorbed titanium peroxide gel and clear, colorless supernatant followed by filtering the mixture to obtain dye or organic pollutant adsorbed titanium peroxide gel;
d) transferring dye or organic pollutant adsorbed titanium peroxide gel as obtained in step (c) in a water containing beaker; and
e) degrading adsorbed dye or organic pollutant from the dye or organic pollutant adsorbed titanium peroxide gel to recover the titanium peroxide gel for reuse.
