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.

Use a lab apron, chemical resistant gloves and goggles before following the below method to dispose of hazardous waste.

 1. Dissolve the substance in the smallest amount of water possible in a beaker placed in a fume hood.
 2. Neutralize the solution to a pH of about 7 with either dilute hydrochloric acid or dilute sodium hydroxide if necessary.
 3. Stir the solution and add an excess of 1 M calcium chloride to the neutral solution. A precipitate will form.
 4. Decant the liquid and flush it down the drain with at least a 20-fold excess of water.
 5. Once the solid has dried, place it in a container and it should be disposed of in a landfill.

Solution Prep

To prepare a solution, determine the formula weight of the material, the concentration (Molarity) of the solution, and the amount of solution desired in Liters. Once this information has been obtained, use the following formula:
(Formula Weight) x (Concentration) x (Desired Volume) = Number of grams in desired volume of liquid

For a 1 M, 1 L solution:
(Formula Weight) x (1 mol/L) x (1 L) = x g added to 1-L volumetric flask. Dilute to a final volume of 1 L with DI Water.
