However there are many chemicals, such as heavy metal compounds or organic solvents, that require special disposal techniques. However, chromic acid will (violently) oxidize alcohols to their respective aldehydes or ketones, which cannot be oxidized further by the acid alone, which limits it's use in neutralizing many compounds. This wiki will NOT take any responsibility (legal or other) for any (failed) attempts at neutralizing hazardous reagents. Section 7: Handling and While this can sometimes be time consuming, it can often be more environmentally and economically friendly than discarding the waste in one manner or another is. Office of Response and Restoration, Sometimes it is an option to purify waste products into chemicals that are pure enough to be used again. Oxidizing mixtures, such as aqua regia, piranha solution or the nitrating mixture must also never be poured down the drain, as they're much more dangerous than simple acids, and can wreak havoc on your plumbing.

Products containing zinc sulfate can be granular, pelleted, tableted, wettable powders, or dusts. Likewise, it's forbidden to burn certain materials in open air, such as aromatic compounds or organosulfur compounds and for those, special incinerators are a must. In the interest of keeping lab costs low, though, it may be a good idea to look into ways to recycle and recover chemicals such as solvents, which can be reclaimed by distillation. They can, however, be converted to aluminium sulfate, which is safe to dispose of in soil, though it will cause a decrease in pH (it is used as a fertilizer for this purpose), and in diluted form can be poured down the drain, as at low concentrations it's used in the treatment of water. Another simple solution is to reduce the ions back to the metal. Section 13 - Disposal Considerations Dispose of in a manner consistent with federal, state, and local regulations.
