Section 13 - Disposal Considerations Dispose of in a manner consistent with federal, state, and local regulations. Filter off green precipitate. In general, your designated place for pouring chemicals into the soil should be far from any gardens, horticulture or any other agricultural objects. WebSaline solution. A good rule of thumb for transition metals is to convert solutions of their ions to the insoluble carbonate or oxide, often one of the most stable and nontoxic forms of these elements, prior to disposal. Generally, the soil option is safer, because there is no plumbing you should worry about, but some chemicals shouldn't be released into the soil, either. It may be a better idea just to recover them by distillation, though. Another simple solution is to reduce the ions back to the metal.
