Disposal

This disposal method is published for your convenience. You MUST have checked with your federal, state, and local regulations before using this method and these methods are only applicable for small laboratory sized quantities.

This material can only be disposed properly by a licensed hazardous waste disposal firm. Check to see if your school or district has an established relationship with a disposal firm and if not, check with a local college/university or other high schools in the area to see who they use to dispose of their hazardous waste.

Solution Prep

To prepare a ninhydrin solution, use a 0.5% alcoholic solution. Add 0.5 g of ninhydrin to 75 ml of n-butyl alcohol or ethyl alcohol or isopropyl alcohol. Heat gently until all the solid is dissolved. Alcohols are a fire risk, so be careful. Dilute to a final volume of 100 ml with the chosen alcohol.
