Project description:
A chemist is required. We need help to solve one problem.
There is a flower dried dark brown, the purpose is to bleach to light green. In a solution of hydrogen peroxide 3% + baking soda bleached well, but when drying it becomes brown again.
You need to fix the color after bleaching, or there may be other ways.
Tried after bleaching in a solution of pectin, as well as agar agar, to no avail, the trick is that the flower is consumed in food and it is necessary to use non-hazardous materials for health, thank you in advance.
